Enum Metadata 

pub enum Metadata {
    String(Vec<u8>),
    Value {
        ty: TypeId,
        value: ValueId,
    },
    Node(Vec<Option<MetadataId>>),
    Distinct(Vec<Option<MetadataId>>),
    Debug {
        distinct: bool,
        node: DebugNode,
    },
}

A metadata record.

Variants

String(Vec<u8>)

A metadata string, as stored (not checked to be UTF-8 here).

Value

A value as metadata.

Fields

ty: TypeId

The value’s type.

value: ValueId

The value.

Node(Vec<Option<MetadataId>>)

Operands; None is a null operand.

Distinct(Vec<Option<MetadataId>>)

A node of its own, never merged with a node of the same operands (METADATA_DISTINCT_NODE: the loop identifiers llvm.loop names, whose first operand is the node itself).

Debug

A debug-information node (a program built with -Zi), and whether it is distinct.

Fields

distinct: bool

The node is distinct (never merged with one of the same fields).

node: DebugNode

The node.

Implementations

impl Metadata

pub fn operands(&self) -> Option<&[Option<MetadataId>]>

The operands of a node of generic operands, distinct or not; None for a string, a value or a debug node (whose operands DebugNode::operands gives).

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metadata

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

Formats the value using the given formatter.

impl PartialEq for Metadata

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

Equality operator ==.

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

Inequality operator !=.
