Implementations§

Source§

impl EventMetadata

Source

pub fn timestamp(&self) -> Option<SystemTime>

Source

pub fn write_header<W: Write>( &self, len: u32, event_type: u16, nparams: u32, writer: W, ) -> Result<()>

Write event header

To form a valid event, after calling this method, the caller must write out the payload at exactly len - 26 bytes, containing nparam lengths (as the proper type) and the parameter values themselves.

Source

pub fn write_header_with_lengths<W: Write, L: Into<u32> + Copy, const N: usize>( &self, event_type: u16, lengths: [L; N], writer: W, ) -> Result<()>

Write event header and parameter lengths

To form a valid event, after calling this method, the caller must write out the payload for each parameter, lengths[i] bytes in length.
