Struct ChunkOptions 

pub struct ChunkOptions {
    pub chunk_dims: Option<Vec<u64>>,
    pub deflate_level: Option<u32>,
    pub shuffle: bool,
    pub fletcher32: bool,
}

Options for chunked dataset creation.

Fields

chunk_dims: Option<Vec<u64>>

Chunk dimensions (one per dataset dimension).

deflate_level: Option<u32>

Deflate compression level (0-9), None = no deflate.

shuffle: bool

Whether to apply shuffle filter before compression.

fletcher32: bool

Whether to apply fletcher32 checksum.

Implementations

impl ChunkOptions

pub fn is_chunked(&self) -> bool

pub fn build_pipeline(&self, element_size: u32) -> Option<FilterPipeline>

Build a FilterPipeline from the options.

pub fn resolve_chunk_dims(&self, shape: &[u64]) -> Vec<u64>

Determine chunk dimensions, using user-specified or auto-computing.
