Struct binout::VByte

pub struct VByte;

Expand description

Serializer that uses improved VByte/LEB128 encoding.

The encoding is identical to the classic VByte/LEB128 for u16 and u32 values. However:

u8 value are always stored as is, using 1 byte.
For u64 values below 2⁶³, the encoding is identical to the classic VByte/LEB128; For larger values, the encoding always stores the most significant byte of value as is, using a total of 9 bytes, whereas a classic VByte could use 10 bytes.
