Implementations

impl PostScript

pub fn footer_length(&self) -> u64

Returns the value of footer_length, or the default value if footer_length is unset.

pub fn compression(&self) -> CompressionKind

Returns the enum value of compression, or the default if the field is unset or set to an invalid enum value.

pub fn set_compression(&mut self, value: CompressionKind)

Sets compression to the provided enum value.

pub fn compression_block_size(&self) -> u64

Returns the value of compression_block_size, or the default value if compression_block_size is unset.

pub fn metadata_length(&self) -> u64

Returns the value of metadata_length, or the default value if metadata_length is unset.

pub fn writer_version(&self) -> u32

Returns the value of writer_version, or the default value if writer_version is unset.

pub fn magic(&self) -> &str

Returns the value of magic, or the default value if magic is unset.
