Enum LibVer 

pub enum LibVer {
    Earliest,
    V18,
    V110,
    V112,
    V114,
}

A library-version boundary, mirroring HDF5’s H5F_libver_t.

Variants are ordered oldest to newest; a later variant understands strictly more of the format than an earlier one. LibVer derives Ord on that ordering, so bounds can be compared directly.

Variants

Earliest

The earliest format (HDF5 1.0+): version 0/1 superblock, v1 symbol-table groups. Readable by every released HDF5 library.

V18

HDF5 1.8: version 2 superblock and the “new style” (version 2) object headers, dense link/attribute storage, and the v2 B-tree indices.

V110

HDF5 1.10: version 3 superblock, plus SWMR and the extensible/fixed array chunk indices. This is the format this crate’s writer emits.

V112

HDF5 1.12.

V114

HDF5 1.14.

Implementations

impl LibVer

pub const LATEST: LibVer = LibVer::V114

The newest boundary this enum knows about — the meaning of H5F_LIBVER_LATEST. Tracks the highest concrete variant.

pub const WRITER_OUTPUT: LibVer = LibVer::V110

The on-disk format this crate’s FileBuilder produces: the version 3 superblock introduced in HDF5 1.10.

pub fn from_superblock_version(version: u8) -> LibVer

The minimum library version required to read a file with the given superblock version — i.e. the low bound the on-disk format implies.

Superblock 0/1 → Earliest; 2 → V18; 3 and anything newer → V110.

pub fn name(self) -> &'static str

A short, stable label for diagnostics (e.g. error messages).

Trait Implementations

impl Clone for LibVer

fn clone(&self) -> LibVer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LibVer

impl Debug for LibVer

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

Formats the value using the given formatter.

impl Eq for LibVer

impl Hash for LibVer

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for LibVer

fn cmp(&self, other: &LibVer) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LibVer

fn eq(&self, other: &LibVer) -> 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.

impl PartialOrd for LibVer

fn partial_cmp(&self, other: &LibVer) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
