Struct FileSpaceInfo 

pub struct FileSpaceInfo {
    pub strategy: FileSpaceStrategy,
    pub persist: bool,
    pub threshold: u64,
    pub page_size: u64,
    pub page_end_meta_threshold: u16,
    pub eoa_pre_fsm: u64,
    pub manager_addrs: Vec<u64>,
}

A parsed (or to-be-written) File Space Info message.

Fields

strategy: FileSpaceStrategy

The file-space management strategy.

persist: bool

Whether free space is persisted to disk across file close (the manager addresses below are written only when this is set).

threshold: u64

Smallest free-space section size the managers track.

page_size: u64

File-space page size used for paged allocation.

page_end_meta_threshold: u16

Page-end metadata threshold (paged allocation tuning).

eoa_pre_fsm: u64

End-of-allocation address recorded before free-space manager metadata was allocated; u64::MAX when free space is not persisted.

manager_addrs: Vec<u64>

Free-space manager header addresses (present only when persist is set); unused slots are u64::MAX. Followed to their on-disk FSHD/ FSSE blocks by File::persisted_free_space.

Trait Implementations

impl Clone for FileSpaceInfo

fn clone(&self) -> FileSpaceInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileSpaceInfo

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

Formats the value using the given formatter.

impl Eq for FileSpaceInfo

impl PartialEq for FileSpaceInfo

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