Struct DavTraversalBudget 

pub struct DavTraversalBudget { /* private fields */ }

Allocation-free recursive traversal budget state.

Implementations

impl DavTraversalBudget

pub fn new(limits: DavTraversalLimits) -> Result<Self, DavTraversalError>

Errors

Returns DavTraversalError when any required traversal limit is zero.

pub const fn progress(self) -> DavTraversalProgress

pub fn checkpoint( &self, cancellation: &impl DavCancellation, ) -> Result<(), DavTraversalError>

Errors

Returns DavTraversalError when cancellation has been requested.

pub fn visit(&mut self, depth: usize) -> Result<(), DavTraversalError>

Errors

Returns DavTraversalError when depth or visited-resource limits are exceeded.

pub fn reserve_work( &mut self, additional: usize, ) -> Result<(), DavTraversalError>

Errors

Returns DavTraversalError when the queued-work counter would exceed its limit.

pub fn complete_work(&mut self)

pub fn record_failure(&mut self) -> Result<(), DavTraversalError>

Errors

Returns DavTraversalError when the failure counter would exceed its limit.

pub fn record_completed_mutation(&mut self)

Trait Implementations

impl Clone for DavTraversalBudget

fn clone(&self) -> DavTraversalBudget

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DavTraversalBudget

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

Formats the value using the given formatter.

impl PartialEq for DavTraversalBudget

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