Struct RowGeometry 

pub struct RowGeometry {
    pub rows: usize,
    pub stride: usize,
    pub row_bytes: usize,
    pub samples: usize,
}

Geometry of a row-structured payload, used to work out how many bytes are needed and how many samples a truncated range still holds.

Fields

rows: usize

Rows in the unit.

stride: usize

Bytes from one row start to the next.

row_bytes: usize

Bytes holding a row’s samples (<= stride; the rest of the stride is padding).

samples: usize

Samples per row.

Implementations

impl RowGeometry

pub fn packed(rows: usize, samples: usize, bits: u32, stride: usize) -> Self

Rows of samples values packed at bits per sample, stride bytes apart.

pub fn tight(rows: usize, samples: usize, bits: u32) -> Self

Tightly packed rows.

pub fn needed(&self) -> usize

Bytes needed for every sample: the last row needs no padding. Saturates.

pub fn total(&self) -> u64

Total samples.

pub fn complete_rows(&self, avail: usize) -> usize

Rows whose samples lie entirely within the first avail bytes.

pub fn complete_samples(&self, avail: usize) -> u64

Samples entirely within the first avail bytes (complete rows plus the complete samples of a partial row).

pub fn missing_samples(&self, avail: usize) -> u64

Samples not covered by the first avail bytes.
