## 0.7.3
- Bump Minimal Supported Rust Version to 1.36 due to dependencies.
- Add support for PDB 2.0 format.

# Rust Debug ID

<a href="https://crates.io/crates/debugid"><img src="https://img.shields.io/crates/v/debugid.svg" alt=""></a>
This crate implements a type that is a thin wrapper around uuids that
can hold a "debug id". This is a concept that originally comes from
breakpad and is also used by Sentry to identify a debug information
file.

//! This crate provides types for identifiers of object files, such as executables, dynamic
//! libraries or debug companion files. The concept originates in Google Breakpad and defines two
//! types:
//!
//! - [`CodeId`]: Identifies the file containing source code, i.e. the actual library or
//! executable. The identifier is platform dependent and implementation defined. Thus, there is
//! no canonical representation.
//! - [`DebugId`]: Identifies a debug information file, which may or may not use information from
//! the Code ID. The contents are also implementation defined, but as opposed to `CodeId`, the
//! structure is streamlined across platforms. It is also guaranteed to be 32 bytes in size.
//!
//! [`CodeId`]: struct.CodeId.html
//! [`DebugId`]: struct.DebugId.html

/// exact rules around this are complex. On Windows, the identifiers are completely different and
/// refer to separate files.
///
/// The string representation must be between 33 and 40 characters long and consist of:
///
/// 1. 36 character hyphenated hex representation of the UUID field
/// 2. 1-16 character lowercase hex representation of the u32 appendix
///
/// The debug identifier is compatible to Google Breakpad. Use [`DebugId::breakpad`] to get a
/// breakpad string representation of this debug identifier.
///
/// There is one exception to this: for the old PDB 2.0 format the debug identifier consists
/// of only a 32-bit integer + age resulting in a string representation of between 9 and 16
/// hex characters.

/// ```
