Struct MessageAttributeValue

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

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 SendMessage.

Name, type, value and the message body must not be empty or null. All parts of the message attribute, including Name, Type, and Value, are part of the message size restriction (256 KiB or 262,144 bytes).

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.

string_value: Option<String>

Strings are Unicode with UTF-8 binary encoding. For a list of code values, see ASCII Printable Characters.

binary_value: Option<Blob>

Binary type attributes can store any binary data, such as compressed data, encrypted data, or images.

string_list_values: Option<Vec<String>>

Not implemented. Reserved for future use.

binary_list_values: Option<Vec<Blob>>

Not implemented. Reserved for future use.

data_type: String

Amazon SQS supports the following logical data types: String, Number, and Binary. For the Number data type, you must use StringValue.

You can also append custom labels. For more information, see Amazon SQS Message Attributes in the Amazon SQS Developer Guide.

Implementations

impl MessageAttributeValue

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

Strings are Unicode with UTF-8 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, such as compressed data, encrypted data, or images.

pub fn string_list_values(&self) -> &[String]

Not implemented. Reserved for future use.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .string_list_values.is_none().

pub fn binary_list_values(&self) -> &[Blob]

Not implemented. Reserved for future use.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .binary_list_values.is_none().

pub fn data_type(&self) -> &str

Amazon SQS supports the following logical data types: String, Number, and Binary. For the Number data type, you must use StringValue.

You can also append custom labels. For more information, see Amazon SQS Message Attributes in the Amazon SQS Developer Guide.

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.
