Struct rustc_mir_transform::dest_prop::WriteInfo

struct WriteInfo {
    writes: Vec<Local>,
    skip_pair: Option<(Local, Local)>,
}

Describes where a statement/terminator writes to

Fields

writes: Vec<Local>

skip_pair: Option<(Local, Local)>

If this pair of locals is a candidate pair, completely skip processing it during this statement. All other candidates are unaffected.

Implementations

impl WriteInfo

fn for_statement<'tcx>(
    &mut self,
    statement: &StatementKind<'tcx>,
    body: &Body<'tcx>
)

    &mut self,
    lhs: Place<'tcx>,
    rhs: &Operand<'tcx>,
    body: &Body<'tcx>
)

fn for_terminator<'tcx>(&mut self, terminator: &TerminatorKind<'tcx>)

fn add_place<'tcx>(&mut self, place: Place<'tcx>)

fn add_operand<'tcx>(&mut self, op: &Operand<'tcx>)

fn reset(&mut self)

Trait Implementations

impl Debug for WriteInfo

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

Formats the value using the given formatter.

impl Default for WriteInfo

fn default() -> WriteInfo

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
