Struct PerfRead 

#[non_exhaustive]
pub struct PerfRead {
    pub records: Vec<FrameRecord>,
    pub next: u64,
    pub dropped: u64,
    pub measured: bool,
}

The records a session kept from a number on: a read of its stream.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

records: Vec<FrameRecord>

The kept records numbered since or more, oldest first, the first max of them.

next: u64

The number to read from next time: the one after the last record answered. Less than since when the session started again.

dropped: u64

How many records numbered since or more were no longer kept.

measured: bool

Whether anything was measured.

Implementations

impl PerfRead

pub fn none(since: u64) -> Self

A read of nothing, from since, with nothing measured: a session that doesn’t measure.

pub fn of(ring: &PerfRing, since: u64, max: u32) -> Self

The first max records of ring numbered since or more. A since past the ring’s next number (a ring of a game started again) reads nothing, with next 0.

Trait Implementations

impl Clone for PerfRead

fn clone(&self) -> PerfRead

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PerfRead

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PerfRead

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PerfRead

impl JsonSchema for PerfRead

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for PerfRead

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for PerfRead

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
