Implementations

impl Value

source

pub fn new_argument(
 context: &mut Context,
 ty: Type,
 span_md_idx: Option<MetadataIndex>
) -> Value

Return a new argument Value.

source

pub fn new_constant(
 context: &mut Context,
 constant: Constant,
 span_md_idx: Option<MetadataIndex>
) -> Value

Return a new constant Value.

source

pub fn new_instruction(
 context: &mut Context,
 instruction: Instruction,
 opt_span_md_idx: Option<MetadataIndex>
) -> Value

Return a new instruction Value.

source

pub fn get_span(&self, context: &Context) -> Option

Return this value’s source span.

source

pub fn is_constant(&self, context: &Context) -> bool

Return whether this is a constant value.

source

pub fn is_terminator(&self, context: &Context) -> bool

Return whether this value is an instruction, and specifically a ‘terminator’.

A terminator is always the last instruction in a block (and may not appear anywhere else) and is either a branch or return.

source

pub fn replace_instruction_value(
    &self,
    context: &mut Context,
    old_val: Value,
    new_val: Value
)

If this value is an instruction and if any of its parameters is old_val then replace them with new_val.

source

pub fn get_type(&self, context: &Context) -> Option<Type>

Get the type for this value, if found.

Arguments and constants always have a type, but only some instructions do.
