Struct GExprBody 

pub struct GExprBody<T> {
    pub span: Span,
    pub bound_body_regions: usize,
    pub locals: Locals,
    pub body: T,
    pub comments: Vec<(usize, Vec<String>)>,
}

An expression body. TODO: arg_count should be stored in GFunDecl below. But then, the print is obfuscated and Aeneas may need some refactoring.

Fields

span: Span

bound_body_regions: usize

The number of regions existentially bound in this body. We introduce fresh such regions during translation instead of the erased regions that rustc gives us.

locals: Locals

The local variables.

body: T

The statements and blocks that compose this body.

comments: Vec<(usize, Vec<String>)>

For each line inside the body, we record any whole-line // comments found before it. They are added to statements in the late recover_body_comments pass.

Implementations

impl GExprBody<IndexVec<BlockId, BlockData>>

pub fn as_abort_map(&self) -> HashMap<BlockId, AbortKind>

Returns a map from blocks in this body to their abort kind, if they correspond to an abort block (ie. a block with no statements and an TerminatorKind::Abort terminator).

pub fn transform_sequences_fwd<F>(&mut self, f: F)

where F: FnMut(BlockId, &mut Locals, &mut [Statement]) -> Vec<(usize, Vec<Statement>)>,

pub fn transform_sequences_bwd<F>(&mut self, f: F)

where F: FnMut(&mut Locals, &mut [Statement]) -> Vec<(usize, Vec<Statement>)>,

pub fn visit_statements<F: FnMut(&mut Statement)>(&mut self, f: F)

Apply a function to all the statements, in a bottom-up manner.

impl<T> GExprBody<T>

fn fmt_with_ctx_and_callback<C: AstFormatter>( &self, ctx: &C, f: &mut Formatter<'_>, fmt_body: impl FnOnce(&mut Formatter<'_>, &<<C as AstFormatter>::Reborrow<'_> as AstFormatter>::Reborrow<'_>, &T) -> Result, ) -> Result

Trait Implementations

impl<T: Clone> Clone for GExprBody<T>

fn clone(&self) -> GExprBody<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for GExprBody<T>

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

Formats the value using the given formatter.
