Overview ¶
Package conv holds the conversions every database backend uses at its model boundary, so the backends cannot each invent their own.

Functions ¶
func LikePattern ¶
LikePattern turns a search term into a LIKE / ILIKE pattern matching it anywhere, with the wildcards in the term escaped by a backslash.
func MetadataJSON ¶
MetadataJSON is usage metadata as the JSON text a backend stores. A nil map is stored as {}, never null, so every row holds an object.
func ParseCost ¶
ParseCost reads NULL as an unknown cost. It accepts exponent notation because some databases print decimals that way.
func ParseMetadata ¶
ParseMetadata reads what MetadataJSON wrote. An empty or null value, which a row from before metadata existed may hold, reads as an empty, non-nil map.
func ParseOptional ¶
ParseOptional reads NULL and "" as id.Nil. Rows written before attribution was nullable hold "" for "nobody".
func ParseTimeText ¶
ParseTimeText reads TimeText's format.
