Enum CaseContinuation

pub enum CaseContinuation {
    Break,
    FallThrough,
    Continue,
}

Symbol that terminates the body of a case branch and determines what to do after executing it

Variants

Break

;; (terminate the case construct)

FallThrough

;& (unconditionally execute the body of the next case branch)

Continue

;| or ;;& (resume with the next case branch, performing pattern matching again)

Trait Implementations

impl Clone for CaseContinuation

fn clone(&self) -> CaseContinuation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CaseContinuation

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

Formats the value using the given formatter.

impl Default for CaseContinuation

fn default() -> CaseContinuation

Returns the “default value” for a type.

impl Display for CaseContinuation

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

Formats the value using the given formatter.

impl From<CaseContinuation> for Operator

fn from(cc: CaseContinuation) -> Operator

Converts a case continuation into an operator.

The Continue variant is converted into SemicolonBar.

impl PartialEq for CaseContinuation

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

impl TryFrom<Operator> for CaseContinuation

fn try_from(op: Operator) -> Result<CaseContinuation, TryFromOperatorError>

Converts an operator into a case continuation.

The SemicolonBar and SemicolonSemicolonAnd operators are converted into Continue; you cannot distinguish between the two from the return value.

type Error = TryFromOperatorError

The type returned in the event of a conversion error.

impl Copy for CaseContinuation

impl Eq for CaseContinuation

impl StructuralPartialEq for CaseContinuation
