Struct SelectorKey 

pub struct SelectorKey {
    pub kind: u8,
    pub number: u32,
    pub generation: u16,
}

A selector key: an observation kind, its number, and its generation.

Ordering is lexicographic by (kind, number, generation), which is the canonical index order.

Fields

kind: u8

SEL_PAGE, SEL_OBJECT, SEL_STREAM, SEL_STREAM_DECODED, SEL_REVISION, SEL_RESOURCE, SEL_PACKAGE_MEMBER_RAW, SEL_PACKAGE_MEMBER_DECODED, or SEL_OPC_MODEL.

number: u32

The page/object/stream/revision/resource number, or a package member’s central-directory ordinal.

generation: u16

The generation (0 where the kind has none).

Implementations

impl SelectorKey

pub const fn new(kind: u8, number: u32) -> Self

A key with generation 0.

pub const fn with_generation(kind: u8, number: u32, generation: u16) -> Self

A key with an explicit generation.

Trait Implementations

impl Eq for SelectorKey

impl Ord for SelectorKey

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for SelectorKey

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for SelectorKey

fn partial_cmp(&self, other: &Self) -> 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.
