pub fn is_be(&self) -> Option<bool>

Checks if format is big endian.

Returns true when the specified format is big endian, false if little endian. Returns None when endianness does not apply to this format, or if unknown.

pub fn is_ne(&self) -> Option<bool>

Checks if format is native endian.

Returns true when the specified format is native endian, false when not. Returns None when endianness does not apply to the specified format, or endianness is unknown.

pub fn is_re(&self) -> Option<bool>

Checks if format is reverse of native endian.

Returns true when the specified format is reverse endian, false when not. Returns None when endianness does not apply to the specified format, or endianness is unknown.
