Expand description

A FuncWriter used to decorate functions during printing.

Required Methods§

source

fn write_block_header( &mut self, w: &mut dyn Write, func: &Function, block: Block, indent: usize ) -> Result

Write the basic block header for the current function.

source

fn write_instruction( &mut self, w: &mut dyn Write, func: &Function, aliases: &SecondaryMap<Value, Vec<Value>>, inst: Inst, indent: usize ) -> Result

Write the given inst to w.

Provided Methods§

source

fn write_preamble( &mut self, w: &mut dyn Write, func: &Function ) -> Result<bool, Error>

Write the preamble to w. By default, this uses write_entity_definition.

source

fn super_preamble( &mut self, w: &mut dyn Write, func: &Function ) -> Result<bool, Error>

Default impl of write_preamble

source

fn write_entity_definition( &mut self, w: &mut dyn Write, func: &Function, entity: AnyEntity, value: &dyn Display, maybe_fact: Option<&Fact> ) -> Result

Write an entity definition defined in the preamble to w.

source

fn super_entity_definition( &mut self, w: &mut dyn Write, func: &Function, entity: AnyEntity, value: &dyn Display, maybe_fact: Option<&Fact> ) -> Result

Default impl of write_entity_definition
