Module: Context

Context.mutate

Performs a series of mutations on a Context. Prevents unnecessary copying of the underlying map when multiple mutations are needed.

When to use

Use to apply several Context transformations in one callback while copying the underlying service map only once.

See

• add for adding or replacing a service
• addOrOmit for adding or removing a service from an Option
• merge for combining two contexts
• pick for keeping selected services
• omit for removing selected services

Signature

declare const mutate: { <Services, B>(f: (context: Context<Services>) => Context<B>): <Services>(self: Context<Services>) => Context<B>; <Services, B>(self: Context<Services>, f: (context: Context<Services>) => Context<B>): Context<B>; }
