Struct Depth 

pub struct Depth(/* private fields */);

A saturating u32 counter for nesting-depth tracking.

All arithmetic uses saturating semantics: inc() saturates at u32::MAX (effectively unreachable for real documents), and dec() saturates at 0. This prevents underflow when malformed input would otherwise cause it, in line with the project’s fail-fast policy: a stuck-at-zero counter surfaces as an invalid-sequence error downstream rather than a panic.

Implementations

impl Depth

pub fn dec(&mut self)

Saturating decrement by one. Calling on a zero value is a no-op.

pub fn get(self) -> u32

Returns the inner u32 value.

pub fn inc(&mut self)

Saturating increment by one. Calling at u32::MAX is a no-op.

pub fn is_positive(self) -> bool

Returns true when the depth is greater than zero.

pub fn is_zero(self) -> bool

Returns true when the depth is zero.

pub fn reset(&mut self)

Resets the depth to zero. Used when a closing scope guarantees the current nesting level returns to the outermost state.

Trait Implementations

impl Clone for Depth

fn clone(&self) -> Depth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Depth

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

Formats the value using the given formatter.

impl Default for Depth

fn default() -> Depth

Returns the “default value” for a type.

impl PartialEq for Depth

fn eq(&self, other: &Depth) -> 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 Copy for Depth

impl Eq for Depth

impl StructuralPartialEq for Depth
