Enum fidl_fuchsia_diagnostics::StringSelector

pub enum StringSelector {
    StringPattern(String),
    ExactMatch(String),
    // some variants omitted
}

StringSelector is an union defining different ways to describe a pattern to match strings against.

Variants

StringPattern(String)

This is a provided string that defines a pattern to match against. The parser treats asterisks (*), colons (:) and backslashes () as special characters.

If you wish to match against literal asterisks (*), they must be escaped. If you wish to match against literal backslashes (), they must be escaped. If you wish to match against literal colons (:), they must be escaped.

eg: abc will match any string with the exact name “abc”. eg: a* will match any string with the exact name “a*”. eg: a\* will match any that starts with exactly “a". eg: a* will match any string that starts with “a”. eg: ab will match any string that starts with a and ends with b. eg: ab*c will match any string that starts with a and ends with c, with b in the middle.

In addition, the “**” literal is treated as a special sequence that may match multiple levels in a component selector only. See |ComponentSelector| for details.

ExactMatch(String)

This is a provided string that defines an exact string to match against. No characters are treated as special, or carry special syntax.

Implementations

impl StringSelector

pub fn ordinal(&self) -> u64

pub fn unknown_variant_for_testing() -> Self

pub fn is_unknown(&self) -> bool

Trait Implementations

impl Autonull for StringSelector

fn naturally_nullable(_context: &Context) -> bool

Returns true if the type is naturally able to be nullable.

impl Clone for StringSelector

fn clone(&self) -> StringSelector

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StringSelector

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Decodable for StringSelector

fn new_empty() -> Self

Creates a new value of this type with an “empty” representation.

fn decode(&mut self, decoder: &mut Decoder<'_>, offset: usize) -> Result<()>

Decodes an object of this type from the decoder’s buffers into self. Callers must ensure that offset is a multiple of Layout::inline_align, and that decoder.buf has room for reading Layout::inline_size bytes at offset.

impl Encodable for StringSelector

fn encode( &mut self, encoder: &mut Encoder<'_, '_>, offset: usize, recursion_depth: usize ) -> Result<()>

Encode the object into the buffer. Any handles stored in the object are swapped for Handle::INVALID. Callers must ensure that offset is a multiple of Layout::inline_align, and that encoder.buf has room for writing Layout::inline_size bytes at offset.

impl Layout for StringSelector

fn inline_align(_context: &Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(context: &Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for the type’s alignment. Must be a multiple of inline_align.

fn supports_simple_copy() -> boolwhere Self: Sized,

Returns true iff the type can be encoded or decoded via simple copy.

impl PartialEq<StringSelector> for StringSelector

fn eq(&self, other: &Self) -> 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.
