Struct Attributes 

#[non_exhaustive]
pub struct Attributes {
    pub attribute_map: HashMap<String, AttributeValue>,
    pub dropped_attributes_count: i32,
    /* private fields */
}

A set of attributes as key-value pairs.

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.

attribute_map: HashMap<String, AttributeValue>

A set of attributes. Each attribute’s key can be up to 128 bytes long. The value can be a string up to 256 bytes, a signed 64-bit integer, or the boolean values true or false. For example:

"/instance_id": { "string_value": { "value": "my-instance" } }
"/http/request_bytes": { "int_value": 300 }
"abc.com/myattribute": { "bool_value": false }

dropped_attributes_count: i32

The number of attributes that were discarded. Attributes can be discarded because their keys are too long or because there are too many attributes. If this value is 0 then all attributes are valid.

Implementations

impl Attributes

pub fn new() -> Self

pub fn set_attribute_map<T, K, V>(self, v: T) -> Self

where T: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<AttributeValue>,

Sets the value of attribute_map.

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

Sets the value of dropped_attributes_count.

Trait Implementations

impl Clone for Attributes

fn clone(&self) -> Attributes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Attributes

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

Formats the value using the given formatter.

impl Default for Attributes

fn default() -> Attributes

Returns the “default value” for a type.

impl Message for Attributes

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Attributes

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