Struct Path 

pub struct Path<T = MetaForm>
where
    T: Form,
{
    pub segments: Vec<<T as Form>::String>,
}

Represents the path of a type definition.

This consists of several segments that each have to be a valid Rust identifier. The first segment represents the crate name in which the type has been defined. The last segment is the identifier accessed with ident().

Rust prelude type may have an empty namespace definition.

Fields

segments: Vec<<T as Form>::String>

The segments of the namespace.

Implementations

impl Path

pub fn new(ident: &'static str, module_path: &'static str) -> Path

Create a new Path

Panics

• If the type identifier or module path contain invalid Rust identifiers

pub fn new_with_replace( ident: &'static str, module_path: &'static str, segment_replace: &[(&'static str, &'static str)], ) -> Path

Create a new Path

The segment_replace is a list of (search, replace) items. Every search item that appears in the module_path is replaced by the replace item. This can be used for example to replace the crate name or even the name of the type in the final Path.

Panics

• If the type identifier, module path or replace contain invalid Rust identifiers

pub fn from_segments<I>(segments: I) -> Result<Path, PathError>

where I: IntoIterator<Item = <MetaForm as Form>::String>,

Create a Path from the given segments

Errors

• If no segments are supplied
• If any of the segments are invalid Rust identifiers

impl<T> Path<T>

where T: Form,

pub fn from_segments_unchecked<I>(segments: I) -> Path<T>

where I: IntoIterator<Item = <T as Form>::String>,

Create a Path from the given segments.

Does not check that the segments are valid Rust identifiers.

pub fn segments(&self) -> &[<T as Form>::String]

👎Deprecated since 2.5.0: Prefer to access the fields directly; this getter will be removed in the next major version

Returns the segments of the Path

pub fn is_empty(&self) -> bool

Returns true if the path is empty

pub fn ident(&self) -> Option<<T as Form>::String>

Get the ident segment of the Path

pub fn namespace(&self) -> &[<T as Form>::String]

Get the namespace segments of the Path
