Package Usage

Context

First, this context is compatible with built-in context interface. Also it supports fork and commit like trace span.

Fork

Fork will generate a sub context that inherit the parent's tags. When new tags are added to the sub-context, the parent-context will not be affected.

Commit

Commit will log the context duration, and export metrics or other execution information.

usage

tracerCtx:=context.NewTraceContext(stdCtx,"$id") 
defer tracerCtx.Commit("success")

// Execute sub-code logic
subCtx:=tracerCtx.Fork("sub-id")
...
subCtx.Commit("step is executed")
