Struct PortableStoreFormat 

pub struct PortableStoreFormat {
    pub segment_bytes: u64,
    pub index_slots: u64,
}

The sizes a portable file store root is created with. Reopening a root uses the sizes recorded at its creation.

Fields

segment_bytes: u64

Bytes per segment file: at least the maximum record size and below FAT’s 4 GiB file limit. A record never spans segments.

index_slots: u64

Initial slots of the hash index file, a power of two from 64 to 2^28 (a 2 GiB file); the index doubles when it is half full.

Implementations

impl PortableStoreFormat

pub const MAX_SEGMENT_BYTES: u64

FAT’s largest file size.

Trait Implementations

impl Clone for PortableStoreFormat

fn clone(&self) -> PortableStoreFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PortableStoreFormat

impl Debug for PortableStoreFormat

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

Formats the value using the given formatter.

impl Default for PortableStoreFormat

fn default() -> PortableStoreFormat

Returns the “default value” for a type.

impl Eq for PortableStoreFormat

impl PartialEq for PortableStoreFormat

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