Crate ccache_stats_reader

This crate implements a simple interface for accessing ccache stats without needing an exec call.

Experimental testing demonstrates I can produce the same data emitted by ccache --print-stats while also using only ¼ the heap, and less than ½ the stack, while the program itself can call do this multiple times in-process without adding an exec() penalty to everything.

Example Usage

use ccache_stats_reader::{CacheDir,CacheField,CacheFieldCollection};

let stats = CacheDir::read_dir("/home/foo/.ccache/").unwrap();
println!("Direct Cache Hits: {:?}", stats.get_field(CacheField::CacheHitDir));
println!("Cache Last Zero'd: {}", CacheField::ZeroTimeStamp.format_value( stats.get_field(CacheField::ZeroTimeStamp))

Structs

CacheFieldData	A hash-like interface for accessing values using Enums as keys.
CacheFieldMeta	A container for metadata about various fields.
CacheLeaf	A leaf container for one sub-cache of a ccache directory.

Enums

CacheField	An enum based field definition for ccache's data fields.
CacheFieldFormat	A descriptor enum for which formatting to use for a given field.
ErrorKind	An enum for wrapping various errors emitted by this crate.

Traits

CacheFieldCollection

An abstact representation of 'a thing' that can expose data about its unit.
