Functions


Functions appear in expression context and take Zed values as arguments and produce a value as a result.

  • abs - absolute value of a number
  • base64 - encode/decode base64 strings
  • bucket - quantize a time or duration value into buckets of equal widths
  • cast - coerce a value to a different type
  • ceil - ceiling of a number
  • cidr_match - test if IP is in a network
  • compare - return an int comparing two values
  • crop - remove fields from a value that are missing in a specified type
  • error - wrap a value as an error
  • every - bucket ts using a duration
  • fields - return the flattened path names of a record
  • fill - add null values for missing record fields
  • flatten - transform a record into a flattened map
  • floor - floor of a number
  • grep - search strings inside of values
  • has - test existence of values
  • has_error - test if a value has an error
  • is - test a value's type
  • is_error - test if a value is an error
  • join - concatenate array of strings with a separator
  • kind - return a value's type category
  • ksuid - encode/decode KSUID-style unique identifiers
  • len - the type-dependent length of a value

  • parse_uri - parse a string URI into a structured record
  • parse_zson - parse ZSON text into a Zed value
  • pow - exponential function of any base
  • quiet - quiet "missing" errors
  • replace - replace one string for another
  • round - round a number
