Struct BufferBuildShape 

pub struct BufferBuildShape {
    pub acc_param_idx: usize,
    pub acc_param_name: String,
    pub kind: BufferBuildKind,
}

Information about a fn that matches the buffer-build sink shape.

Fields

acc_param_idx: usize

0-based index of the acc: List<T> parameter in the fn signature. Identifies which arg in tail-call positions threads the accumulator and which Ident in the base-case arm is returned.

acc_param_name: String

The accumulator parameter’s binding name (looked up in tail-call args and in the base-case return position).

kind: BufferBuildKind

Which of the two reverse-placement idioms this sink follows; determines (a) what shape the original base arm has and (b) whether the call site is String.join(<sink>(...), sep) or String.join(List.reverse(<sink>(...)), sep).

Trait Implementations

impl Clone for BufferBuildShape

fn clone(&self) -> BufferBuildShape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BufferBuildShape

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

Formats the value using the given formatter.

impl PartialEq for BufferBuildShape

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
