Struct BranchShell 

#[non_exhaustive]
pub struct BranchShell {
    pub keyword: BranchKeyword,
    pub condition_range: SourceLocation,
    pub elsif_count: usize,
    pub has_else: bool,
}

Conditional-branch shell payload.

Models the static shape of an if/unless block statement or a ternary expression: how many alternatives exist and whether a fallthrough else arm is present. It is provider-neutral substrate proof, not an evaluator.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

keyword: BranchKeyword

Surface form that produced this branch.

condition_range: SourceLocation

Source range of the primary condition expression.

elsif_count: usize

Number of elsif alternatives (block form only; 0 for ternary).

has_else: bool

Whether a fallthrough else arm (or ternary else expression) exists.

Trait Implementations

impl Clone for BranchShell

fn clone(&self) -> BranchShell

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BranchShell

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

Formats the value using the given formatter.

impl Eq for BranchShell

impl PartialEq for BranchShell

fn eq(&self, other: &BranchShell) -> 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.
