Struct string_cache_codegen::AtomType

pub struct AtomType { /* private fields */ }

A builder for a static atom set and relevant macros

Implementations

impl AtomType

pub fn new(path: &str, macro_name: &str) -> Self

Constructs a new static atom set builder

path is a path within a crate of the atom type that will be created. e.g. "FooAtom" at the crate root or "foo::Atom" if the generated code is included in a foo module.

macro_name must end with !.

For example, AtomType::new("foo::FooAtom", "foo_atom!") will generate:

pub type FooAtom = ::string_cache::Atom<FooAtomStaticSet>;
pub struct FooAtomStaticSet;
impl ::string_cache::StaticAtomSet for FooAtomStaticSet {
    // ...
}
#[macro_export]
macro_rules foo_atom {
   // Expands to: $crate::foo::FooAtom { … }
}

pub fn with_atom_doc(&mut self, docs: &str) -> &mut Self

Add some documentation to the generated Atom type alias.

This can help the user know that the type uses interned strings.

Note that docs should not contain the /// at the front of normal docs.

pub fn with_static_set_doc(&mut self, docs: &str) -> &mut Self

Add some documentation to the generated static set.

This can help the user know that this type is zero-sized and just references a static lookup table, or point them to the Atom type alias for more info.

Note that docs should not contain the /// at the front of normal docs.

pub fn with_macro_doc(&mut self, docs: &str) -> &mut Self

Add some documentation to the generated macro.

Note that docs should not contain the /// at the front of normal docs.

pub fn atom(&mut self, s: &str) -> &mut Self

Adds an atom to the builder

pub fn atoms<I>(&mut self, iter: I) -> &mut Self where
    I: IntoIterator,
    I::Item: AsRef<str>, 

Adds multiple atoms to the builder

pub fn write_to<W>(&mut self, destination: W) -> Result<()> where
    W: Write, 

Write generated code to destination.

pub fn write_to_file(&mut self, path: &Path) -> Result<()>

Create a new file at path and write generated code there.

Typical usage: .write_to_file(&Path::new(&env::var("OUT_DIR").unwrap()).join("foo_atom.rs"))
