Struct winrt_gen::TypeReader

pub struct TypeReader {
    pub files: Vec<WinmdFile>,
    pub types: BTreeMap<String, BTreeMap<String, TypeDef>>,
}

A reader of type information from Windows Metadata

Fields

files: Vec<WinmdFile>

The parsed Windows metadata files the TypeReader has access to

types: BTreeMap<String, BTreeMap<String, TypeDef>>

Types known to this TypeReader

This is a mapping between namespace names and the types inside that namespace

Implementations

impl TypeReader

pub fn from_os() -> Self

pub fn new(files: Vec<WinmdFile>) -> Self

Create a new TypeReader from a WinmdFiles

pub fn namespaces(&self) -> impl Iterator<Item = &String>

Get all the namespace names that the TypeReader knows about

pub fn namespace_types(
    &self,
    namespace: &str
) -> impl Iterator<Item = (&str, &TypeDef)>

Get all type definitions ([TypeDef]s) for a given namespace

Panics

Panics if the namespace does not exist

pub fn resolve_type_def(&self, (namespace, type_name): (&str, &str)) -> TypeDef

Resolve a type definition given its namespace and type name

Panics

Panics if no type definition for the given namespace and type name can be found

pub fn u32(&self, row: Row, column: u32) -> u32

Read a u32 value from a specific [Row] and column

pub fn str(&self, row: Row, column: u32) -> &str

Read a [&str] value from a specific [Row] and column

pub fn decode<T: Decode>(&self, row: Row, column: u32) -> T
