Modules

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

Macros

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

Structs

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.

Traits

ToHex

Convert to hex

Functions

from_hex

Decode a hex string into bytes.

to_base64

Encode an utf8 string to a base64 string

Type Definitions

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.
