Struct PsiSample

pub struct PsiSample {
    pub resource: Option<i32>,
    pub total_ns: Option<u64>,
}

Reading from /proc/pressure/*.

Fields

resource: Option<i32>

total_ns: Option<u64>

Total absolute stall time (in nanos) for a given resource. While PSI readings are in micros, we store in nanos for consistency with most other time-based counters.

Implementations

impl PsiSample

pub fn resource(&self) -> PsiResource

Returns the enum value of resource, or the default if the field is unset or set to an invalid enum value.

pub fn set_resource(&mut self, value: PsiResource)

Sets resource to the provided enum value.

pub fn total_ns(&self) -> u64

Returns the value of total_ns, or the default value if total_ns is unset.

Trait Implementations

impl Clone for PsiSample

fn clone(&self) -> PsiSample

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PsiSample

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

Formats the value using the given formatter.

impl Default for PsiSample

fn default() -> Self

Returns the “default value” for a type.

impl Message for PsiSample

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for PsiSample

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

Tests for self and other values to be equal, and is used by ==.

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

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