Struct FrameIndex 

pub struct FrameIndex {
    pub offsets: Vec<u64>,
    pub data_len: u64,
}

Frame start offsets for one data file, plus its total length.

Fields

offsets: Vec<u64>

Byte offset of each frame start, strictly increasing.

data_len: u64

Length of the data in bytes; the last frame ends here.

Implementations

impl FrameIndex

pub fn len(&self) -> usize

Number of frames.

pub fn is_empty(&self) -> bool

True when the index has no frames.

pub fn range(&self, i: usize) -> Option<Range<usize>>

Byte range [start, end) of frame i.

pub fn scan(text: &str) -> Result<Self, ParseError>

Scan text for frame starts, failing on the first malformed frame.
