Struct ed25519_dalek::pkcs8::spki::der::asn1::PrintableStringRef

pub struct PrintableStringRef<'a> { /* private fields */ }

Available on crate feature pkcs8 only.

ASN.1 PrintableString type.

Supports a subset the ASCII character set (described below).

For UTF-8, use Utf8StringRef instead. For the full ASCII character set, use Ia5StringRef.

This is a zero-copy reference type which borrows from the input data.

Supported characters

The following ASCII characters/ranges are supported:

• A..Z
• a..z
• 0..9
• “ ” (i.e. space)
• \
• (
• )
• +
• ,
• -
• .
• /
• :
• =
• ?

fn from(value: &PrintableStringRef<'a>) -> PrintableStringRef<'a>

Converts to this type from the input type.

impl<'a> From<PrintableStringRef<'a>> for AnyRef<'a>

impl<'a> Ord for PrintableStringRef<'a>

fn cmp(&self, other: &PrintableStringRef<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<'a> PartialEq for PrintableStringRef<'a>

fn eq(&self, other: &PrintableStringRef<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
