Struct BufferId 

pub struct BufferId(pub u32);

Stable monotonic handle identifying one buffer instance. Two buffers with the same BufferKind still have distinct ids. The App allocates these via BufferId::next at buffer- creation time and stores them on each buffer + on every position-history entry.

Tuple Fields

0: u32

Implementations

impl BufferId

pub fn next() -> BufferId

Allocate a fresh id. Process-global, monotonic, never recycled (collision impossible inside one process lifetime short of 2^32 buffer creations).

Trait Implementations

impl Clone for BufferId

fn clone(&self) -> BufferId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BufferId

impl Debug for BufferId

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

Formats the value using the given formatter.

impl Default for BufferId

fn default() -> BufferId

Returns the “default value” for a type.

impl Eq for BufferId

impl Hash for BufferId

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for BufferId

fn cmp(&self, other: &BufferId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for BufferId

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for BufferId

fn partial_cmp(&self, other: &BufferId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
