From 67055c47da2c94188540847b33921af25652156a Mon Sep 17 00:00:00 2001 From: Marco Groppo Date: Sun, 24 Mar 2019 22:21:22 +0100 Subject: Target only the actual operator. Renamed `BinExpr::op()` and `PrefixExpr::op()` to `op_kind`. Now `op()` returns the `SyntaxNode`. --- crates/ra_syntax/src/ast.rs | 78 ++++++++++++++++++++++++++------------------- 1 file changed, 45 insertions(+), 33 deletions(-) (limited to 'crates/ra_syntax/src/ast.rs') diff --git a/crates/ra_syntax/src/ast.rs b/crates/ra_syntax/src/ast.rs index d8c2cb063..226208700 100644 --- a/crates/ra_syntax/src/ast.rs +++ b/crates/ra_syntax/src/ast.rs @@ -521,7 +521,7 @@ pub enum PrefixOp { } impl PrefixExpr { - pub fn op(&self) -> Option { + pub fn op_kind(&self) -> Option { match self.syntax().first_child()?.kind() { STAR => Some(PrefixOp::Deref), EXCL => Some(PrefixOp::Not), @@ -529,6 +529,10 @@ impl PrefixExpr { _ => None, } } + + pub fn op(&self) -> Option<&SyntaxNode> { + self.syntax().first_child() + } } #[derive(Copy, Clone, Debug, PartialEq, Eq, Hash)] @@ -598,46 +602,54 @@ pub enum BinOp { } impl BinExpr { - pub fn op(&self) -> Option { + fn op_details(&self) -> Option<(&SyntaxNode, BinOp)> { self.syntax() .children() .filter_map(|c| match c.kind() { - PIPEPIPE => Some(BinOp::BooleanOr), - AMPAMP => Some(BinOp::BooleanAnd), - EQEQ => Some(BinOp::EqualityTest), - NEQ => Some(BinOp::NegatedEqualityTest), - LTEQ => Some(BinOp::LesserEqualTest), - GTEQ => Some(BinOp::GreaterEqualTest), - L_ANGLE => Some(BinOp::LesserTest), - R_ANGLE => Some(BinOp::GreaterTest), - PLUS => Some(BinOp::Addition), - STAR => Some(BinOp::Multiplication), - MINUS => Some(BinOp::Subtraction), - SLASH => Some(BinOp::Division), - PERCENT => Some(BinOp::Remainder), - SHL => Some(BinOp::LeftShift), - SHR => Some(BinOp::RightShift), - CARET => Some(BinOp::BitwiseXor), - PIPE => Some(BinOp::BitwiseOr), - AMP => Some(BinOp::BitwiseAnd), - DOTDOT => Some(BinOp::RangeRightOpen), - DOTDOTEQ => Some(BinOp::RangeRightClosed), - EQ => Some(BinOp::Assignment), - PLUSEQ => Some(BinOp::AddAssign), - SLASHEQ => Some(BinOp::DivAssign), - STAREQ => Some(BinOp::MulAssign), - PERCENTEQ => Some(BinOp::RemAssign), - SHREQ => Some(BinOp::ShrAssign), - SHLEQ => Some(BinOp::ShlAssign), - MINUSEQ => Some(BinOp::SubAssign), - PIPEEQ => Some(BinOp::BitOrAssign), - AMPEQ => Some(BinOp::BitAndAssign), - CARETEQ => Some(BinOp::BitXorAssign), + PIPEPIPE => Some((c, BinOp::BooleanOr)), + AMPAMP => Some((c, BinOp::BooleanAnd)), + EQEQ => Some((c, BinOp::EqualityTest)), + NEQ => Some((c, BinOp::NegatedEqualityTest)), + LTEQ => Some((c, BinOp::LesserEqualTest)), + GTEQ => Some((c, BinOp::GreaterEqualTest)), + L_ANGLE => Some((c, BinOp::LesserTest)), + R_ANGLE => Some((c, BinOp::GreaterTest)), + PLUS => Some((c, BinOp::Addition)), + STAR => Some((c, BinOp::Multiplication)), + MINUS => Some((c, BinOp::Subtraction)), + SLASH => Some((c, BinOp::Division)), + PERCENT => Some((c, BinOp::Remainder)), + SHL => Some((c, BinOp::LeftShift)), + SHR => Some((c, BinOp::RightShift)), + CARET => Some((c, BinOp::BitwiseXor)), + PIPE => Some((c, BinOp::BitwiseOr)), + AMP => Some((c, BinOp::BitwiseAnd)), + DOTDOT => Some((c, BinOp::RangeRightOpen)), + DOTDOTEQ => Some((c, BinOp::RangeRightClosed)), + EQ => Some((c, BinOp::Assignment)), + PLUSEQ => Some((c, BinOp::AddAssign)), + SLASHEQ => Some((c, BinOp::DivAssign)), + STAREQ => Some((c, BinOp::MulAssign)), + PERCENTEQ => Some((c, BinOp::RemAssign)), + SHREQ => Some((c, BinOp::ShrAssign)), + SHLEQ => Some((c, BinOp::ShlAssign)), + MINUSEQ => Some((c, BinOp::SubAssign)), + PIPEEQ => Some((c, BinOp::BitOrAssign)), + AMPEQ => Some((c, BinOp::BitAndAssign)), + CARETEQ => Some((c, BinOp::BitXorAssign)), _ => None, }) .next() } + pub fn op_kind(&self) -> Option { + self.op_details().map(|t| t.1) + } + + pub fn op(&self) -> Option<&SyntaxNode> { + self.op_details().map(|t| t.0) + } + pub fn lhs(&self) -> Option<&Expr> { children(self).nth(0) } -- cgit v1.2.3
