[][src]Struct sgx_tstd::ffi::OsStr

pub struct OsStr { /* fields omitted */ }

Borrowed reference to an OS string (see OsString).

This type represents a borrowed reference to a string in the operating system's preferred representation.

&OsStr is to OsString as &str is to String: the former in each pair are borrowed references; the latter are owned strings.

See the module's toplevel documentation about conversions for a discussion on the traits which OsStr implements for conversions from/to native representations.

Methods

impl OsStr[src]

pub fn new<S: AsRef<OsStr> + ?Sized>(s: &S) -> &OsStr[src]

Coerces into an OsStr slice.

pub fn to_str(&self) -> Option<&str>[src]

Yields a &str slice if the OsStr is valid Unicode.

This conversion may entail doing a check for UTF-8 validity.

pub fn to_string_lossy(&self) -> Cow<str>[src]

Converts an OsStr to a Cow<str>.

Any non-Unicode sequences are replaced with U+FFFD REPLACEMENT CHARACTER.

pub fn to_os_string(&self) -> OsString[src]

Copies the slice into an owned OsString.

pub fn is_empty(&self) -> bool[src]

Checks whether the OsStr is empty.

pub fn len(&self) -> usize[src]

Returns the length of this OsStr.

Note that this does not return the number of bytes in the string in OS string form.

The length returned is that of the underlying storage used by OsStr. As discussed in the OsString introduction, OsString and OsStr store strings in a form best suited for cheap inter-conversion between native-platform and Rust string forms, which may differ significantly from both of them, including in storage size and encoding.

This number is simply useful for passing to other methods, like OsString::with_capacity to avoid reallocations.

pub fn into_os_string(self: Box<OsStr>) -> OsString[src]

Converts a Box<OsStr> into an OsString without copying or allocating.

pub fn make_ascii_lowercase(&mut self)[src]

Converts this string to its ASCII lower case equivalent in-place.

ASCII letters 'A' to 'Z' are mapped to 'a' to 'z', but non-ASCII letters are unchanged.

To return a new lowercased value without modifying the existing one, use to_ascii_lowercase.

pub fn make_ascii_uppercase(&mut self)[src]

Converts this string to its ASCII upper case equivalent in-place.

ASCII letters 'a' to 'z' are mapped to 'A' to 'Z', but non-ASCII letters are unchanged.

To return a new uppercased value without modifying the existing one, use to_ascii_uppercase.

pub fn to_ascii_lowercase(&self) -> OsString[src]

Returns a copy of this string where each character is mapped to its ASCII lower case equivalent.

ASCII letters 'A' to 'Z' are mapped to 'a' to 'z', but non-ASCII letters are unchanged.

To lowercase the value in-place, use make_ascii_lowercase.

pub fn to_ascii_uppercase(&self) -> OsString[src]

Returns a copy of this string where each character is mapped to its ASCII upper case equivalent.

ASCII letters 'a' to 'z' are mapped to 'A' to 'Z', but non-ASCII letters are unchanged.

To uppercase the value in-place, use make_ascii_uppercase.

pub fn is_ascii(&self) -> bool[src]

Checks if all characters in this string are within the ASCII range.

pub fn eq_ignore_ascii_case<S: ?Sized + AsRef<OsStr>>(&self, other: &S) -> bool[src]

Checks that two strings are an ASCII case-insensitive match.

Same as to_ascii_lowercase(a) == to_ascii_lowercase(b), but without allocating and copying temporaries.
