//! Record kind discriminants for the binary log format.
//!
//! Each record in the decompressed binlog stream begins with a 7-bit encoded
//! integer identifying its kind. Changing any discriminant value is a breaking
//! change — these values are part of the on-disk format.

/// Indicates the type of record stored in the binary log.
///
/// There is a record type for each type of build event and also a few
/// meta-data record types (string data, name-value-list data, EOF).
