Trait for string types that provide various operations

Required Methods

fn as_ref_type(&self) -> &S

Borrow a string reference as &S

fn as_bytes(&self) -> &[u8]

Borrow the string as bytes

fn into_owned_type(self) -> <S as ToOwned>::Owned

where <S as ToOwned>::Owned: From<Box<S>>,

Consume a string and convert it to an owned string. S::to_owned is called on Borrowed/Inlined/RefCounted variants. Boxed variants are converted directly into S::Owned (most likely without copy or allocation).

fn to_owned_type(&self) -> <S as ToOwned>::Owned

Convert a string reference to an owned string. S::to_owned is called on all variants.

Provided Methods

fn is_empty(&self) -> bool

Returns true if this is an empty string

fn len(&self) -> usize

Returns the length of this string in bytes

fn as_str(&self) -> &str

where S: AsRef<str>,

Borrow the string as an &str

fn as_os_str(&self) -> &OsStr

where S: AsRef<OsStr>,

Available on crate features std and osstr only.

Borrow the string as an &OsStr

fn as_path(&self) -> &Path

where S: AsRef<Path>,

Available on crate features std and path only.

Borrow the string as a &Path

fn as_c_str(&self) -> &CStr

where S: AsRef<CStr>,

Available on crate feature cstr only.

Borrow the string as a &CStr

fn into_string(self) -> String

where <S as ToOwned>::Owned: Into<String> + From<Box<S>>,

Consume a string and convert it to a String

fn into_os_string(self) -> OsString

where <S as ToOwned>::Owned: Into<OsString> + From<Box<S>>,

Available on crate features std and osstr only.

Consume a string and convert it to an OsString

fn into_path_buf(self) -> PathBuf

where <S as ToOwned>::Owned: Into<PathBuf> + From<Box<S>>,

Available on crate features std and path only.

Consume a string and convert it to a PathBuf

fn into_c_string(self) -> CString

where <S as ToOwned>::Owned: Into<CString> + From<Box<S>>,

Available on crate feature cstr only.

Consume a string and convert it to a CString

fn into_vec_bytes(self) -> Vec<u8>

where <S as ToOwned>::Owned: Into<Vec<u8>> + From<Box<S>>,

Available on crate feature bytes only.

Consume a string and convert it to a Vec<u8>

fn to_string(&self) -> String

where <S as ToOwned>::Owned: Into<String>,

Convert a string reference to a String

fn to_os_string(&self) -> OsString

where <S as ToOwned>::Owned: Into<OsString>,

Available on crate features std and osstr only.

Convert a string reference to an OsString

fn to_path_buf(&self) -> PathBuf

where <S as ToOwned>::Owned: Into<PathBuf>,

Available on crate features std and path only.

Convert a string reference to a PathBuf

fn to_c_string(&self) -> CString

where <S as ToOwned>::Owned: Into<CString>,

Available on crate feature cstr only.

Convert a string reference to a CString

fn to_vec_bytes(&self) -> Vec<u8>

where <S as ToOwned>::Owned: Into<Vec<u8>>,

Available on crate feature bytes only.

Convert a string reference to a Vec<u8>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
