BlockingProvider

BlockingSeedProvider

Bush

A collection of tiny logs (twigs) consisting of one trunk and maybe some leaves. There can only ever be one trunk. Trunks are created by planting a twig. Whenever a leaf sprouts, it will appear as a tag on every log message until clipped.

CompositeTwig

Since there can only ever be one trunk on the bush of twigs, this class lets you cheat and make that trunk be a bundle of twigs.

SeedGenerator

This is intentionally insecure. Wallet makers have told us storing keys is their specialty so we don't put a lot of energy here. A true implementation would create a key using user interaction, perhaps with a password they know that is never stored, along with requiring user authentication for key use (i.e. fingerprint/PIN/pattern/etc). From there, one of these approaches might be helpful to store the key securely:

SilentTwig

A tiny log that does nothing. No one hears this twig fall in the woods.

SimpleProvider

TroubleshootingTwig

A tiny log for detecting troubles. Aim at your troubles and pull the twigger.

Twig

A tiny log.

ZcashSdk

Wrapper for all the constant values in the SDK. It is important that these values stay fixed for all users of the SDK. Otherwise, if individual wallet makers are using different values, it becomes easier to reduce privacy by segmenting the anonymity set of users, particularly as it relates to network requests.

ZcashSdkCommon

Wrapper for all the constant values in the SDK. It is important that these values stay fixed for all users of the SDK. Otherwise, if individual wallet makers are using different values, it becomes easier to reduce privacy by segmenting the anonymity set of users, particularly as it relates to network requests.

kotlinx.coroutines.flow.Flow

currencyFormatter

Create a number formatter for use with converting currency to strings. This probably isn't needed externally since the other formatting functions leverage this, instead. Leverages the default rounding mode for zec found in ZEC_FORMATTER.

retrySimple

Execute the given block and if it fails, retry up to retries more times, using thread sleep instead of suspending. If none of the retries succeed then throw the final error. This function is intended to be called with no parameters, i.e., it is designed to use its defaults.

retryUpTo

Execute the given block and if it fails, retry up to retries more times. If none of the retries succeed then throw the final error, which can be wrapped in order to add more context.

retryWithBackoff

Execute the given block and if it fails, retry with an exponential backoff.

spiffy

A tiny log formatter that makes twigs pretty spiffy.

twig

Makes a tiny log.

Times a tiny log.

Times a tiny log. Execute the block of code on the clock.

twigTask

Meticulously times a tiny task.

A tiny log task. Execute the block of code with some twigging around the outside. For silent twigs, this adds a small amount of overhead at the call site but still avoids logging.
