Struct TruncatableString

#[non_exhaustive]
pub struct TruncatableString {
    pub value: String,
    pub truncated_byte_count: i32,
}

Represents a string that might be shortened to a specified length.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

value: String

The shortened string. For example, if the original string is 500 bytes long and the limit of the string is 128 bytes, then value contains the first 128 bytes of the 500-byte string.

Truncation always happens on a UTF8 character boundary. If there are multi-byte characters in the string, then the length of the shortened string might be less than the size limit.

truncated_byte_count: i32

The number of bytes removed from the original string. If this value is 0, then the string was not shortened.

Implementations

impl TruncatableString

pub fn set_value<T: Into<String>>(self, v: T) -> Self

Sets the value of value.

pub fn set_truncated_byte_count<T: Into<i32>>(self, v: T) -> Self

Sets the value of truncated_byte_count.

Trait Implementations

impl Clone for TruncatableString

fn clone(&self) -> TruncatableString

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TruncatableString

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

Formats the value using the given formatter.

impl Default for TruncatableString

fn default() -> TruncatableString

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TruncatableString

where TruncatableString: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for TruncatableString

fn typename() -> &'static str

The typename of this message.

impl PartialEq for TruncatableString

fn eq(&self, other: &TruncatableString) -> 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 Serialize for TruncatableString

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
