Enum yash_env::stack::Frame

#[non_exhaustive]
pub enum Frame {
    Loop,
    Subshell,
    Condition,
    Builtin(Builtin),
    DotScript,
    Trap(Condition),
}

Element of runtime execution context stack

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Loop

For, while, or until loop

Subshell

Subshell

Condition

Context where the ErrExit option is ignored

This frame is pushed when executing negated commands, the condition part of and-or lists and the if, while, and until commands.

Builtin(Builtin)

Built-in utility

DotScript

Shell script file executed by the . built-in

Trap(Condition)

Trap

Trait Implementations

impl Clone for Frame

fn clone(&self) -> Frame

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Frame

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

Formats the value using the given formatter.

impl From<Builtin> for Frame

fn from(builtin: Builtin) -> Self

Converts to this type from the input type.

impl From<Condition> for Frame

fn from(condition: Condition) -> Self

Converts to this type from the input type.

impl PartialEq for Frame

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Eq for Frame

impl StructuralPartialEq for Frame
