//! Minidump structure definitions. //! //! Types defined here should match those defined in [Microsoft's headers][msdn]. Additionally //! some [Breakpad][breakpad] and [Crashpad][crashpad] extension types are defined here and should //! match the definitions from those projects. //! //! # Type Layouts //! //! This library isn't a "proper" minidump-sys library because it doesn't use repr attributes //! to force Rust to layout these structs identically to how they're laid out in memory. //! //! The reasons for this are 3-fold: //! //! 1. It isn't necessary because we specify how to serialize/deserialize things with `scroll` //! via `derive(Pread, Pwrite)` which uses the declared field order and not the in-memory //! layout, and assumes everything is packed anyway, which as a rule, minidump types are. //! Specifically they're packed to align 4, but Microsoft is mercifully very attentive to //! its type layouts so we're not aware of anywhere where packing to align 1 would change //! offsets. Packing is mostly just there so 32-bit and 64-bit definitely agree on offsets. //! //! 2. We would have to mark several types as `repr(packed(4))`, making them dangerous to use //! as several of the fields would become misaligned. This would create a bunch of //! unnecessary and brittle `unsafe`. //! //! 3. It's not *actually* that useful to have structs with precise in-memory layouts since //! a minidump parser needs to accept both little-endian and big-endian minidumps, and //! is therefore swizzling the bytes of all the values anyway. Also it's dangerous to //! reinterpret a pile of memory as arbitrary types without validation! //! //! [msdn]: https://docs.microsoft.com/en-us/windows/win32/api/minidumpapiset/ //!
