FsTypeRef (Xantham) | Xantham

FsTypeRef Type

Namespace: Xantham.Generator
Assembly: Xantham.Generator.dll
Base Type: obj
All Interfaces: IEquatable<FsTypeRef> , IStructuralEquatable , IComparable<FsTypeRef> , IComparable , IStructuralComparable

The F# type written at a reference position. Phase B covers primitives, `option`, arrays, delegates (D5) and references to declarations this run generates; everything else widens to `FsObj` with a finding saying so.

Union cases

Union case	Description
`FsApp(string, FsTypeRef list)` Full Usage: `FsApp(string, FsTypeRef list)` Parameters: Item1 : `string` Item2 : `FsTypeRef list`	A generic declaration applied to arguments: `Box` (§4.9). The checker substitutes members eagerly, so this is written only when the instantiation's target is itself a declaration this run generates; otherwise the expansion stands on its own. Item1 : `string` Item2 : `FsTypeRef list`
`FsArray FsTypeRef` Full Usage: `FsArray FsTypeRef` Parameters: Item : `FsTypeRef`	Item : `FsTypeRef`
`FsBigInt` Full Usage: `FsBigInt`	TypeScript's `bigint`. Exact: Fable 5 compiles F# `bigint` to the native JavaScript `BigInt` - read off the emitted `BigInt.js` (`typeof x === "bigint"`, `fromInt32 n` is `BigInt(n)`) and run against a JS object handing one over, not recalled.
`FsBool` Full Usage: `FsBool`
`FsBranded(primitive, measure)` Full Usage: `FsBranded(primitive, measure)` Parameters: primitive : `FsTypeRef` measure : `string`	A primitive carrying a unit of measure: the F# rendering of a TypeScript branding intersection (§4.6, D11). `string & { __brand: "UserId" }` is a value that is a string at runtime and refuses to substitute for another string at compile time, which is what a measure is. The measure name is a declaration this run emits. primitive : `FsTypeRef` measure : `string`
`FsDelegate(FsTypeRef list, FsTypeRef)` Full Usage: `FsDelegate(FsTypeRef list, FsTypeRef)` Parameters: Item1 : `FsTypeRef list` Item2 : `FsTypeRef`	A callback as a delegate (D5): parameter types and return. Renders as `System.Action`/`System.Func` so the arity is guaranteed at the Fable boundary. Item1 : `FsTypeRef list` Item2 : `FsTypeRef`
`FsErasedUnion FsTypeRef list` Full Usage: `FsErasedUnion FsTypeRef list` Parameters: Item : `FsTypeRef list`	A heterogeneous union as Fable's erased `U2`-`U4` (D4, §4.5(4)). The threshold is four; wider unions widen to `obj`. Arms are distinct - a union whose arms collapse to one F# type is that type instead. Item : `FsTypeRef list`
`FsFloat` Full Usage: `FsFloat`
`FsNamed string` Full Usage: `FsNamed string` Parameters: Item : `string`	Item : `string`
`FsObj` Full Usage: `FsObj`
`FsOption FsTypeRef` Full Usage: `FsOption FsTypeRef` Parameters: Item : `FsTypeRef`	Item : `FsTypeRef`
`FsString` Full Usage: `FsString`
`FsTuple FsTypeRef list` Full Usage: `FsTuple FsTypeRef list` Parameters: Item : `FsTypeRef list`	A fixed-length tuple (D7, §4.12): Fable compiles an F# tuple to a JS array, so the mapping is exact. Optional tail elements arrive already `option`-wrapped, because the checker hands them over as `T \| undefined`. Item : `FsTypeRef list`
`FsTypeVar string` Full Usage: `FsTypeVar string` Parameters: Item : `string`	A type variable in scope - a type parameter of the declaration being shaped (§4.9). Carries the name TypeScript spelled, without the leading tick the renderer adds. Item : `string`
`FsUnit` Full Usage: `FsUnit`
