# smile: file(1) magic for Smile serialization
|
|
#
|
|
# The Smile serialization format uses a 4-byte header:
|
|
#
|
|
# Constant byte #0: 0x3A (ASCII ':')
|
|
# Constant byte #1: 0x29 (ASCII ')')
|
|
# Constant byte #2: 0x0A (ASCII linefeed, '\n')
|
|
# Variable byte #3, consisting of bits:
|
|
# Bits 4-7 (4 MSB): 4-bit version number
|
|
# Bits 3: Reserved
|
|
# Bit 2 (mask 0x04): Whether raw binary (unescaped 8-bit) values may be present in content
|
|
# Bit 1 (mask 0x02): Whether shared String value checking was enabled during encoding, default false
|
|
# Bit 0 (mask 0x01): Whether shared property name checking was enabled during encoding, default true
|
