Crate canton_core 

Core types shared across the Canton Rust SDK.

The foundation the client crates build on: the Error type with its retriable classification and the Result alias, the telemetry layer (tracing spans + metrics), and the shared connection kernel — Config, Auth/TokenSource, TlsConfig, and the retry pipeline — that both canton-ledger and canton-admin build their gRPC channels from.

Modules

auth

Request authentication for gRPC channels.

config

Shared client connection configuration (the Option-B connection kernel).

localnet

Reading a local development network out of the environment.

retry

Opt-in retry with exponential backoff.

telemetry

Telemetry: tracing spans, metrics, and structured events for client calls.

Structs

ErrorInfo

Structured google.rpc.ErrorInfo details from a gRPC status: the machine- readable reason, its domain, and error metadata. #[non_exhaustive].

ResourceInfo

A resource a failure is about, from a google.rpc.ResourceInfo detail on a gRPC status or an entry of a JSON API error body’s resources. #[non_exhaustive].

Enums

Error

The single error type for the whole Canton Rust SDK.

ErrorCategory

Canton’s error categories — the coarse classification every Ledger API error carries (ErrorInfo.metadata["category"]), which the error-code documentation defines retryability on. #[non_exhaustive]: Canton may add categories.

Type Aliases

Result

SDK-wide result alias. Re-exported by the facade as canton::Result.
