Struct puffin::StreamInfo

pub struct StreamInfo {
    pub stream: Stream,
    pub num_scopes: usize,
    pub depth: usize,
    pub range_ns: (NanoSecond, NanoSecond),
}

TODO: Improve encapsulation. A Stream plus some info about it.

Fields

stream: Stream

The raw profile data.

num_scopes: usize

Total number of scopes in the stream.

depth: usize

The depth of the deepest scope. 0 mean no scopes, 1 some scopes without children, etc.

range_ns: (NanoSecond, NanoSecond)

The smallest and largest nanosecond value in the stream.

The default value is (NanoSecond::MAX, NanoSecond::MIN) which indicates an empty stream.

Implementations

impl StreamInfo

pub fn parse(stream: Stream) -> Result<StreamInfo>

Parse a stream to count the depth, number of scopes in it etc.

Try to avoid calling this, and instead keep score while collecting a StreamInfo.

pub fn extend(&mut self, other: &StreamInfoRef<'_>)

Extends this StreamInfo with another StreamInfo.

pub fn clear(&mut self)

Clears the contents of this StreamInfo.

pub fn as_stream_into_ref(&self) -> StreamInfoRef<'_>

Returns a reference to the contents of this StreamInfo.

Trait Implementations

impl Clone for StreamInfo

fn clone(&self) -> StreamInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for StreamInfo

fn default() -> Self

Returns the “default value” for a type.
