Struct DebugTags 

pub struct DebugTags { /* private fields */ }

Debug tags for instructions.

Implementations

impl DebugTags

pub fn set(&mut self, inst: Inst, tags: impl IntoIterator<Item = DebugTag>)

Set the tags on an instruction, overwriting existing tag list.

Tags can only be set on call instructions (those for which [crate::Opcode::is_call()] returns true) and on sequence_point instructions. This property is checked by the CLIF verifier.

pub fn get(&self, inst: Inst) -> &[DebugTag]

Get the tags associated with an instruction.

pub fn has(&self, inst: Inst) -> bool

Does the given instruction have any tags?

pub fn clone_tags(&mut self, from: Inst, to: Inst)

Clone the tags from one instruction to another.

This clone is cheap (references the same underlying storage) because the tag lists are immutable.

pub fn is_empty(&self) -> bool

Are any debug tags present?

This is used for adjusting margins when pretty-printing CLIF.

pub fn clear(&mut self)

Clear all tags.

Trait Implementations

impl Clone for DebugTags

fn clone(&self) -> DebugTags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for DebugTags

fn default() -> DebugTags

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DebugTags

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for DebugTags

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DebugTags

fn eq(&self, other: &DebugTags) -> 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 DebugTags

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
