Enum RirArgMode 

pub enum RirArgMode {
    Normal,
    MutRef,
    Ref,
}

Argument passing mode in RIR.

Mirrors RirParamMode: MutRef / Ref are vestigial-but-used markers carried alongside arguments whose ref-ness cannot be encoded in the AIR value type (interface forwarding) so codegen still routes them through the by-pointer ABI.

Variants

Normal

Normal pass-by-value argument (or a &x / &mut x whose ref-ness is already in the AIR value type).

MutRef

Exclusive mutable reborrow forwarded to a MutRef-mode parameter.

Ref

Shared immutable reborrow forwarded to a Ref-mode parameter.

Trait Implementations

impl Clone for RirArgMode

fn clone(&self) -> RirArgMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RirArgMode

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

Formats the value using the given formatter.

impl Default for RirArgMode

fn default() -> RirArgMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RirArgMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RirArgMode

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RirArgMode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for RirArgMode

impl Eq for RirArgMode
