Supported characters

The following ASCII characters/ranges are supported:

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

const TAG: Tag = Tag::PrintableString

ASN.1 tag

impl<'a> From<&PrintableString<'a>> for PrintableString<'a>

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

Converts to this type from the input type.

impl<'a> From<PrintableString<'a>> for &'a [u8]

fn from(printable_string: PrintableString<'a>) -> &'a [u8]

Converts to this type from the input type.

impl<'a> From<PrintableString<'a>> for Any<'a>

fn from(printable_string: PrintableString<'a>) -> Any<'a>

Converts to this type from the input type.

impl<'a> Ord for PrintableString<'a>

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

impl<'a> PartialEq<PrintableString<'a>> for PrintableString<'a>

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

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.
