Enum RecursionResult 

pub enum RecursionResult {
    Entered,
    Cycle,
    DepthExceeded,
    IterationExceeded,
}

Result of attempting to enter a recursive computation.

Variants

Entered

Proceed with the computation.

Cycle

This key is already being visited — cycle detected.

DepthExceeded

Maximum recursion depth exceeded.

IterationExceeded

Maximum iteration count exceeded.

Implementations

impl RecursionResult

pub const fn is_entered(self) -> bool

Returns true if entry was successful.

pub const fn is_cycle(self) -> bool

Returns true if a cycle was detected.

pub const fn is_exceeded(self) -> bool

Returns true if any limit was exceeded (depth or iterations).

pub const fn is_denied(self) -> bool

Returns true if entry was denied for any reason (cycle or exceeded).

Trait Implementations

impl Clone for RecursionResult

fn clone(&self) -> RecursionResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecursionResult

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

Formats the value using the given formatter.

impl PartialEq for RecursionResult

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