[−][src]Crate grin_util

Logging, as well as various low-level utilities that factor Rust patterns that are frequent within the grin codebase.

file	File util
logger	Logging wrapper to be used throughout all crates in the workspace
macros	Macros to support Rust BIP-32 code (though could conceivably be used for other things)
secp_static	Globally accessible static instance of secp256k1, to avoid initialization overhead
types	Zeroing String
zip	Compress and decompress zip bz2 archives

impl_array_newtype	gives a newtype array wrapper standard array traits
impl_array_newtype_encodable	gives a newtype array wrapper serialization and deserialization methods
impl_array_newtype_show	gives a newtype array wrapper the Debug trait
impl_index_newtype	gives a newtype array wrapper Index traits

OneTime	Encapsulation of a RwLock<Option> for one-time initialization. This implementation will purposefully fail hard if not used properly, for example if not initialized before being first used (borrowed).
RateCounter	A rate counter tracks the number of transfers, the amount of data exchanged and the rate of transfer (via a few timers) over the last minute. The counter does not try to be accurate and update times proactively, instead it only does so lazily. As a result, produced rates are worst-case estimates.
StopState	Global stopped/paused state shared across various subcomponents of Grin.

Convert to hex

from_hex	Decode a hex string into bytes.
to_base64	Encode an utf8 string to a base64 string

Mutex	A mutual exclusion primitive useful for protecting shared data
RwLock	A reader-writer lock
RwLockReadGuard	RAII structure used to release the shared read access of a lock when dropped.
RwLockWriteGuard	RAII structure used to release the exclusive write access of a lock when dropped.
