A kind of Yul statement.

Variants

Block(Block<'ast>)

A blocked scope: { ... }.

Reference: https://docs.soliditylang.org/en/latest/grammar.html#a4.SolidityParser.yulBlock

AssignSingle(AstPath<'ast>, Expr<'ast>)

A single-variable assignment statement: x := 1.

Reference: https://docs.soliditylang.org/en/latest/grammar.html#a4.SolidityParser.yulAssignment

AssignMulti(&'ast mut RawThinSlice<(), AstPath<'ast>>, Expr<'ast>)

A multiple-variable assignment statement: x, y, z := foo(1, 2).

Multi-assignments require a function call on the right-hand side.

Reference: https://docs.soliditylang.org/en/latest/grammar.html#a4.SolidityParser.yulAssignment

Expr(Expr<'ast>)

An expression statement. This can only be a function call.

If(Expr<'ast>, Block<'ast>)

An if statement: if lt(a, b) { ... }.

Reference: https://docs.soliditylang.org/en/latest/grammar.html#a4.SolidityParser.yulIfStatement

For(&'ast mut StmtFor<'ast>)

A for statement: for {let i := 0} lt(i,10) {i := add(i,1)} { ... }.

Reference: https://docs.soliditylang.org/en/latest/grammar.html#a4.SolidityParser.yulForStatement

Switch(StmtSwitch<'ast>)

A switch statement: switch expr case 0 { ... } default { ... }.

Reference: https://docs.soliditylang.org/en/latest/grammar.html#a4.SolidityParser.yulSwitchStatement

Leave

A leave statement: leave.

Break

A break statement: break.

Continue

A continue statement: continue.

FunctionDef(Function<'ast>)

A function definition statement: function f() { ... }.

VarDecl(&'ast mut RawThinSlice<(), Ident>, Option<Expr<'ast>>)

A variable declaration statement: let x := 0.
