Enum perfetto_consumer_proto::perfetto::protos::trace_config::buffer_config::FillPolicy

#[repr(i32)]
pub enum FillPolicy {
    Unspecified = 0,
    RingBuffer = 1,
    Discard = 2,
}

Variants

Unspecified = 0

RingBuffer = 1

Default behavior. The buffer operates as a conventional ring buffer. If the writer is faster than the reader (or if the reader reads only after tracing is stopped) newly written packets will overwrite old packets.

Discard = 2

Behaves like RING_BUFFER as long as there is space in the buffer or the reader catches up with the writer. As soon as the writer hits an unread chunk, it stops accepting new data in the buffer.

Implementations

impl FillPolicy

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of FillPolicy.

pub fn from_i32(value: i32) -> Option<FillPolicy>

Converts an i32 to a FillPolicy, or None if value is not a valid variant.

impl FillPolicy

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

Trait Implementations

impl Clone for FillPolicy

fn clone(&self) -> FillPolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FillPolicy

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

Formats the value using the given formatter.

impl Default for FillPolicy

fn default() -> FillPolicy

Returns the “default value” for a type.

impl From<FillPolicy> for i32

fn from(value: FillPolicy) -> i32

Converts to this type from the input type.

impl Hash for FillPolicy

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

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 FillPolicy

fn cmp(&self, other: &FillPolicy) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for FillPolicy

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for FillPolicy

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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