Enum c2rust_refactor::rewrite::ExprPrec

pub enum ExprPrec {
    Normal(i8),
    Cond(i8),
    Callee(i8),
    LeftLess(i8),
}

Precedence information about the context surrounding an expression. Used to determine whether an expr needs to be parenthesized.

Variants

Normal(i8)

Normal behavior. Parenthesize expr if its precedence is less than the given value.

Cond(i8)

Conditional-like position. Parenthesize lower precedence, and also parenthesize exprs with outer struct literals.

Callee(i8)

Callee position. Parenthesize lower precedence, and also parenthesize struct and tuple field expressions (so the call is not mistaken for a method call).

LeftLess(i8)

Left of < or <<. We have to parenthesize casts in this position because the less than is interpreted as the start of generic arguments.

Trait Implementations

impl Eq for ExprPrec

impl Copy for ExprPrec

impl PartialEq<ExprPrec> for ExprPrec

fn eq(&self, other: &ExprPrec) -> bool

This method tests for self and other values to be equal, and is used by ==.

This method tests for !=.

impl Clone for ExprPrec

fn clone(&self) -> ExprPrec

Returns a copy of the value.

default fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExprPrec

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
