Struct MessageAttributeValue

#[non_exhaustive]
pub struct MessageAttributeValue {
    pub data_type: String,
    pub string_value: Option<String>,
    pub binary_value: Option<Blob>,
}

The user-specified message attribute value. For string data types, the value attribute has the same restrictions on the content as the message body. For more information, see Publish.

Name, type, and value must not be empty or null. In addition, the message body should not be empty or null. All parts of the message attribute, including name, type, and value, are included in the message size restriction, which is currently 256 KB (262,144 bytes). For more information, see Amazon SNS message attributes and Publishing to a mobile phone in the Amazon SNS Developer Guide.

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.

data_type: String

Amazon SNS supports the following logical data types: String, String.Array, Number, and Binary. For more information, see Message Attribute Data Types.

string_value: Option<String>

Strings are Unicode with UTF8 binary encoding. For a list of code values, see ASCII Printable Characters.

binary_value: Option<Blob>

Binary type attributes can store any binary data, for example, compressed data, encrypted data, or images.

Implementations

impl MessageAttributeValue

pub fn data_type(&self) -> &str

Amazon SNS supports the following logical data types: String, String.Array, Number, and Binary. For more information, see Message Attribute Data Types.

pub fn string_value(&self) -> Option<&str>

Strings are Unicode with UTF8 binary encoding. For a list of code values, see ASCII Printable Characters.

pub fn binary_value(&self) -> Option<&Blob>

Binary type attributes can store any binary data, for example, compressed data, encrypted data, or images.

impl MessageAttributeValue

pub fn builder() -> MessageAttributeValueBuilder

Creates a new builder-style object to manufacture MessageAttributeValue.

Trait Implementations

impl Clone for MessageAttributeValue

fn clone(&self) -> MessageAttributeValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageAttributeValue

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

Formats the value using the given formatter.

impl PartialEq for MessageAttributeValue

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