Struct WriteOptions

pub struct WriteOptions { /* private fields */ }

Options that can be passed to the writer to customize written output

Implementations

impl WriteOptions

pub fn set_size_byte_count(len: usize) -> WriteOptions

Specifies the byte length for the element’s “size”

This function generates WriteOptions that will force the Element Data Size to be a specific number of bytes for the written tag.

Panics

This method asserts that len is within 1-8 (inclusive). Values outside this range will cause a panic.

pub fn is_unknown_sized_element() -> WriteOptions

Specifies that the element has an Unknown Data Size.

The WriteOptions generated by this function allow you to start a tag that doesn’t have a known size. Useful for streaming, or when the data is expected to be too large to fit into memory. This should only be used with Master type tags.
