StringRules describe the constraints applied to string values

Fields

const: Option<String>

Const specifies that this field must be exactly the specified value

len: Option<u64>

Len specifies that this field must be the specified number of characters (Unicode code points). Note that the number of characters may differ from the number of bytes in the string.

min_len: Option<u64>

MinLen specifies that this field must be the specified number of characters (Unicode code points) at a minimum. Note that the number of characters may differ from the number of bytes in the string.

max_len: Option<u64>

MaxLen specifies that this field must be the specified number of characters (Unicode code points) at a maximum. Note that the number of characters may differ from the number of bytes in the string.

len_bytes: Option<u64>

LenBytes specifies that this field must be the specified number of bytes at a minimum

min_bytes: Option<u64>

MinBytes specifies that this field must be the specified number of bytes at a minimum

max_bytes: Option<u64>

MaxBytes specifies that this field must be the specified number of bytes at a maximum

pattern: Option<String>

Pattern specifes that this field must match against the specified regular expression (RE2 syntax). The included expression should elide any delimiters.

prefix: Option<String>

Prefix specifies that this field must have the specified substring at the beginning of the string.

suffix: Option<String>

Suffix specifies that this field must have the specified substring at the end of the string.

contains: Option<String>

Contains specifies that this field must have the specified substring anywhere in the string.

not_contains: Option<String>

NotContains specifies that this field cannot have the specified substring anywhere in the string.

in: Vec<String>

In specifies that this field must be equal to one of the specified values

not_in: Vec<String>

NotIn specifies that this field cannot be equal to one of the specified values

strict: Option<bool>

This applies to regexes HTTP_HEADER_NAME and HTTP_HEADER_VALUE to enable strict header validation. By default, this is true, and HTTP header validations are RFC-compliant. Setting to false will enable a looser validations that only disallows \r\n\0 characters, which can be used to bypass header matching rules.

ignore_empty: Option<bool>

IgnoreEmpty specifies that the validation rules of this field should be evaluated only if the field is not empty

well_known: Option<WellKnown>

WellKnown rules provide advanced constraints against common string patterns

Trait Implementations

impl Clone for StringRules

fn clone(&self) -> StringRules

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StringRules

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

Formats the value using the given formatter.

impl Default for StringRules

fn default() -> Self

Returns the “default value” for a type.

impl Message for StringRules

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

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

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for StringRules

fn eq(&self, other: &StringRules) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl ReflectMessage for StringRules

fn descriptor(&self) -> MessageDescriptor

Gets a MessageDescriptor describing the type of this message.

fn transcode_to_dynamic(&self) -> DynamicMessage

where Self: Sized,

Converts this message into an instance of DynamicMessage by going through the byte representation.
