Struct FrameIndex 

pub struct FrameIndex {
    pub total_padded_size: u64,
    pub entries: Vec<FrameIndexEntry>,
}

Fields

total_padded_size: u64

S3 上の object 全体サイズ (padding frame 含む)

entries: Vec<FrameIndexEntry>

Implementations

impl FrameIndex

pub fn total_original_size(&self) -> u64

pub fn lookup_range(&self, start: u64, end_exclusive: u64) -> Option<RangePlan>

Range request [start, end_exclusive) を解決して必要 frame の (start_idx, end_idx_exclusive) と S3 上の partial-fetch byte range [byte_start, byte_end_exclusive) を返す。

1 frame でもオーバーラップしていればその frame の 全 byte を fetch する (= 部分 frame は decompress 単位)。

Trait Implementations

impl Clone for FrameIndex

fn clone(&self) -> FrameIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameIndex

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

Formats the value using the given formatter.

impl Default for FrameIndex

fn default() -> FrameIndex

Returns the “default value” for a type.

impl PartialEq for FrameIndex

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