Struct FileAccessOptions 

pub struct FileAccessOptions { /* private fields */ }

File-access options applied when opening an HDF5 file.

This is the hdf5-pure analogue of the HDF5 file access property list settings relevant to read-time memory usage. The metadata cache only affects streaming opens; in-memory opens already have the whole file in one buffer. The chunk cache is the file-wide default corresponding to HDF5 H5Pset_cache’s raw-data chunk-cache settings and applies to datasets opened from either backend.

Implementations

impl FileAccessOptions

pub const fn new() -> Self

Create options with the crate’s default access behavior.

pub const fn with_metadata_cache( self, metadata_cache: MetadataCacheConfig, ) -> Self

Configure the bounded streaming metadata cache.

pub const fn with_chunk_cache(self, chunk_cache: ChunkCacheConfig) -> Self

Configure the per-dataset raw chunk cache used by datasets opened from this file. This is the H5Pset_cache-style file-wide default.

pub const fn metadata_cache(&self) -> MetadataCacheConfig

Return the configured streaming metadata cache.

pub const fn chunk_cache(&self) -> ChunkCacheConfig

Return the configured per-dataset chunk cache.

Trait Implementations

impl Clone for FileAccessOptions

fn clone(&self) -> FileAccessOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for FileAccessOptions

impl Debug for FileAccessOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FileAccessOptions

fn default() -> FileAccessOptions

Returns the “default value” for a type.

impl Eq for FileAccessOptions

impl PartialEq for FileAccessOptions

fn eq(&self, other: &FileAccessOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
