Crate jaq_std

Standard library for a JSON query language.

The standard library provides a set of filters. These filters are either implemented as definitions or as functions. For example, the standard library provides the map(f) filter, which is defined using the more elementary filter [.[] | f].

Macros

• ow
  Convenience macro for once_with which creates a closure and maps errors to exceptions.

Traits

• ValT
  Values that the core library can operate on.

Functions

• base_funs
  Minimal set of filters that are generic over the value type. Return the minimal set of named filters available in jaq which are implemented as native filters, such as length, keys, …, but not now, debug, fromdateiso8601, …
• defs
  Definitions of the standard library.
• extra_funs
  Supplementary set of filters that are generic over the value type.
• funs
  Return those named filters available by default in jaq which are implemented as native filters, such as length, keys, …, but also now, debug, fromdateiso8601, …
• once_with
  Return a boxed iterator that lazily evaluates the given function.
• run
  Convert a filter with a run pointer to a native filter.
• unary
  Create a filter that takes a single variable argument and whose output is given by the function f that takes the input value and the value of the variable.
• v
  Creates n variable arguments.
