Struct WriteOptions 

pub struct WriteOptions {
    pub format_version: String,
    pub standard_version: String,
    pub write_block_index: bool,
    pub write_checksums: bool,
    pub emit: EmitOptions,
    pub tree_padding: usize,
    pub asdf_library: Option<Software>,
}

How to write a file.

Fields

format_version: String

The version written on the #ASDF header line.

standard_version: String

The version written on the #ASDF_STANDARD comment line.

write_block_index: bool

Write a block index after the last block.

write_checksums: bool

Compute and store each block’s MD5 checksum.

emit: EmitOptions

How the YAML tree is laid out.

tree_padding: usize

Bytes of padding between the tree and the first block, so the tree can grow later without rewriting the whole file.

asdf_library: Option<Software>

The asdf_library provenance to record, unless the tree already has one.

Every ASDF writer stamps the file with what wrote it, and readers act on it: the workaround for the Python checksum bug keys off exactly this field. None writes nothing, which is what a caller reproducing another writer’s output wants.
