Module solana_libra_vm::file_format_common

Constants for the binary format.

Definition for the constants of the binary format, used by the serializer and the deserializer. This module also offers helpers for the serialization and deserialization of certain integer indexes.

We use LEB128 for integer compression. LEB128 is a representation from the DWARF3 spec, http://dwarfstd.org/Dwarf3Std.php or https://en.wikipedia.org/wiki/LEB128. It's used to compress mostly indexes into the main binary tables.

Structs

BinaryData

A wrapper for the binary vector

Enums

BinaryConstants	Constant values for the binary format header.
Opcodes	List of opcodes constants.
SerializedKind
SerializedNativeStructFlag
SerializedNominalResourceFlag
SerializedType	Constants for signature blob values.
SignatureType	Constants for signature kinds (type, function, locals). Those values start a signature blob.
TableType	Constants for table types in the binary.

Constants

BINARY_SIZE_LIMIT

Upper limit on the binary size

Functions

read_uleb128_as_u16	Reads a u16 in ULEB128 format from a binary.
read_uleb128_as_u32	Reads a u32 in ULEB128 format from a binary.
write_u16	Write a u16 in Little Endian format.
write_u32	Write a u32 in Little Endian format.
write_u64	Write a u64 in Little Endian format.
write_u16_as_uleb128	Take a Vec<u8> and a value to write to that vector and applies LEB128 logic to compress the u16.
write_u32_as_uleb128	Take a Vec<u8> and a value to write to that vector and applies LEB128 logic to compress the u32.
