Struct TagRow 

#[non_exhaustive]
pub struct TagRow {
    pub class: TagClass,
    pub name: Cow<'static, str>,
    pub live_bytes: u64,
    pub live_blocks: u32,
    pub allocated_bytes: u64,
    pub peak_bytes: u64,
}

One memory tag’s counts in a HeapSnapshot, in bytes asked for. Build it with TagRow::new (ADR-0039).

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.

class: TagClass

What the tag names: a phase, a span, an asset kind, or other.

name: Cow<'static, str>

Its name: update, the span’s (ai), the asset kind’s (image), other or overflow.

live_bytes: u64

The bytes live under it: allocated, or last grown, under it and not yet freed.

live_blocks: u32

The blocks live under it.

allocated_bytes: u64

The bytes ever allocated under it: a block grown adds its new size.

peak_bytes: u64

The most bytes live under it at once.

Implementations

impl TagRow

pub fn new( class: TagClass, name: impl Into<Cow<'static, str>>, live_bytes: u64, live_blocks: u32, ) -> Self

class’s name with live_bytes live in live_blocks blocks, as if just allocated: its bytes ever allocated and its peak are its live bytes (assign them otherwise).

Trait Implementations

impl Clone for TagRow

fn clone(&self) -> TagRow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TagRow

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TagRow

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TagRow

impl JsonSchema for TagRow

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 TagRow

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for TagRow

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
