MmapParser

Struct MmapParser 

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

Memory-mapped file parser for large files

Uses OS-level memory mapping for efficient access to large files without loading entire file into memory.

§Examples

use aion_context::parser::MmapParser;

let parser = MmapParser::open("large_file.aion")?;
let header = parser.header();
println!("File ID: {}", header.file_id);

Implementations§

Source§

impl MmapParser

Source

pub fn open<P: AsRef<Path>>(path: P) -> Result<Self>

§Errors

Returns error if:

  • File cannot be opened
  • File cannot be memory-mapped
  • Header parsing fails
§Examples
use aion_context::parser::MmapParser;

let parser = MmapParser::open("file.aion")?;
