Enum ExprShape 

pub enum ExprShape {
    Call {
        callee: CalleeShape,
        argc: usize,
    },
    MethodCall {
        method: String,
        argc: usize,
    },
    Path,
    Lit,
    Other,
}

A normalized expression shape used by paragraph statements.

Variants

Call

A function call with known or unknown callee identity and arity.

Fields

callee: CalleeShape

argc: usize

MethodCall

Fields

method: String

argc: usize

Path

A stable path expression.

Lit

Other

A present expression shape outside the supported model.

Implementations

impl ExprShape

pub const fn call(callee: CalleeShape, argc: usize) -> Self

Builds a function-call expression shape.

Examples

use whitaker_common::rstest::{CalleeShape, ExprShape};

let shape = ExprShape::call(CalleeShape::def_path("crate::make_user"), 2);
assert_eq!(
    shape,
    ExprShape::Call {
        callee: CalleeShape::def_path("crate::make_user"),
        argc: 2,
    },
);

pub fn method_call(method: impl Into<String>, argc: usize) -> Self

Builds a method-call expression shape.

pub const fn path() -> Self

Builds a path expression shape.

pub const fn lit() -> Self

Builds a literal expression shape.

pub const fn other() -> Self

Builds an explicit unsupported expression shape.
