ResultList (issie)

ResultList Module

Namespace: global
Assembly: Renderer.dll
Parent Module: Helpers

Running a list of operations that can fail, stopping at the first Error. Written out by hand this is a fold over Result whose accumulator is built with `got @ [x]`, which is quadratic and was repeated in half a dozen places. These are linear and are the only version.

Functions and values

Function or value	Description
`fold f state items` Full Usage: `fold f state items` Parameters: f : `'s -> 'a -> Result<'s, 'e>` state : `'s` items : `'a list` Returns: `Result<'s, 'e>`	Thread a state through `f` for each item in turn. The first Error stops the walk and is returned; later items are not visited. f : `'s -> 'a -> Result<'s, 'e>` state : `'s` items : `'a list` Returns: `Result<'s, 'e>`
`iter f items` Full Usage: `iter f items` Parameters: f : `'a -> Result<unit, 'e>` items : `'a list` Returns: `Result<unit, 'e>`	Apply `f` to every item for its effect only. f : `'a -> Result<unit, 'e>` items : `'a list` Returns: `Result<unit, 'e>`
`sequence results` Full Usage: `sequence results` Parameters: results : `Result<'a, 'e> list` Returns: `Result<'a list, 'e>`	The list of Oks, or the first Error. results : `Result<'a, 'e> list` Returns: `Result<'a list, 'e>`
`traverse f items` Full Usage: `traverse f items` Parameters: f : `'a -> Result<'b, 'e>` items : `'a list` Returns: `Result<'b list, 'e>`	Apply `f` to every item, collecting the results in order. f : `'a -> Result<'b, 'e>` items : `'a list` Returns: `Result<'b list, 'e>`
