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
• coalesce - return first value that is not null, a "missing" error, or a "quiet" error
• 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

• 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
• levenshtein Levenshtein distance
