FileRangeReader

Struct FileRangeReader 

Source
pub struct FileRangeReader { /* private fields */ }
Expand description

Simple file reader that seeks and reads for each request.

This reader has minimal memory overhead but may have higher I/O latency when reading many small ranges. For sequential access patterns, consider using BufferedRangeReader instead.

§Example

use mdf4_rs::{MdfIndex, FileRangeReader};

let index = MdfIndex::from_file_streaming("data.mf4")?;
let mut reader = FileRangeReader::new("data.mf4")?;
let values = index.read_channel_values(0, 0, &mut reader)?;

Implementations§
