Source
pub struct VarLong { /* private fields */ }
Expand description

Represents a Java Long (i64) using between 1-10 bytes.

Implementations§

Source§

impl VarLong

Source

pub fn value(self) -> i64

Returns the value of a given VarLong

Source

pub fn from_bytes(data: &[u8]) -> Result<(VarLong, usize), Error>

Creates a VarLong from a series of bytes. Returns the value and the amount of bytes used if creation is successful.

Source

pub fn from_reader<R: Read>(reader: &mut R) -> Result<VarLong, Error>

Creates a VarLong from a reader containing bytes.

Source

pub fn to_writer<W: Write>(&mut self, writer: &mut W) -> Result<(), Error>

Writes a VarLong to a writer as a series of bytes.

Source

pub fn to_bytes(self) -> Result<Vec<u8>, Error>

Converts a VarLong to a series of bytes.

Source

pub fn from_value(value: i64) -> Result<VarLong, Error>

Creates a VarLong from a given value.

Source

pub fn read_size(&self) -> Option<u8>
