Struct GExprBody

pub struct GExprBody<T> {
    pub span: Span,
    pub arg_count: usize,
    pub locals: Vector<VarId, Var>,
    pub comments: Vec<(usize, Vec<String>)>,
    pub body: T,
}

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

arg_count: usize

The number of local variables used for the input arguments.

locals: Vector<VarId, Var>

The local variables. We always have, in the following order:

• the local used for the return value (index 0)
• the input arguments
• the remaining locals, used for the intermediate computations

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.

body: T

Implementations

impl GExprBody<Vector<BlockId, BlockData>>

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

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

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

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

Trait Implementations

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

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

Returns a copy 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.

impl<'de, T> Deserialize<'de> for GExprBody<T>

where T: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: Drive> Drive for GExprBody<T>

fn drive<V: Visitor>(&self, visitor: &mut V)

impl<T: DriveMut> DriveMut for GExprBody<T>

fn drive_mut<V: VisitorMut>(&mut self, visitor: &mut V)

impl<T, C> FmtWithCtx<C> for GExprBody<T>

where C: for<'a> SetLocals<'a>, for<'a, 'a, 'b> <C as SetLocals<'a>>::C: AstFormatter + Formatter<&'b T>,

fn fmt_with_ctx(&self, ctx: &C) -> String

fn fmt_with_ctx_and_indent(&self, tab: &str, ctx: &C) -> String

fn with_ctx<'a>(&'a self, ctx: &'a C) -> impl Display + 'a

Returns a struct that implements Display. This allows the following:

impl<'a> Formatter<&GExprBody<Block>> for FmtCtx<'a>

fn format_object(&self, body: &ExprBody) -> String

impl<'a> Formatter<&GExprBody<Vector<BlockId, BlockData>>> for FmtCtx<'a>

fn format_object(&self, body: &ExprBody) -> String

impl<T> Serialize for GExprBody<T>

where T: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
