Struct MmapParser 

pub struct MmapParser { /* private fields */ }

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

impl MmapParser

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

Open and memory-map a file

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")?;
