Implementations§

source§

impl<'a> Block

source

pub fn new(offset: i64, metaDataLength: i32, bodyLength: i64) -> Self

source

pub fn offset(&self) -> i64

Index to the start of the RecordBlock (note this is past the Message header)

source

pub fn set_offset(&mut self, x: i64)

source

pub fn metaDataLength(&self) -> i32

Length of the metadata

source

pub fn set_metaDataLength(&mut self, x: i32)

source

pub fn bodyLength(&self) -> i64

Length of the data (this is aligned so there can be a gap between this and the metadata).

source

pub fn set_bodyLength(&mut self, x: i64)

impl PartialEq for Block

source§

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