Struct LifecycleFilter 

pub struct LifecycleFilter {
    pub prefix: Option<String>,
    pub tags: Vec<(String, String)>,
    pub object_size_greater_than: Option<u64>,
    pub object_size_less_than: Option<u64>,
}

Per-rule object filter. AWS S3 represents the filter as one of Prefix, Tag, ObjectSizeGreaterThan, ObjectSizeLessThan, or And (= AND of any subset of those predicates). For internal storage we flatten the “And” form into a struct of optional fields plus a vector of (key, value) tags — every present field must match (logical AND). An empty filter (all fields None / empty tags) matches every object in the bucket.

Fields

prefix: Option<String>

Object key prefix (empty / None = no prefix gating).

tags: Vec<(String, String)>

Logical AND across every entry: every (key, value) must match the object’s own tag set.

object_size_greater_than: Option<u64>

Object must be strictly greater than this size in bytes.

object_size_less_than: Option<u64>

Object must be strictly less than this size in bytes.

Implementations

impl LifecycleFilter

pub fn matches( &self, key: &str, size: u64, object_tags: &[(String, String)], ) -> bool

true when this filter accepts the candidate. Empty filter accepts every object. Tag matching is AND of all listed tags (each present in object_tags with the matching value).

Trait Implementations

impl Clone for LifecycleFilter

fn clone(&self) -> LifecycleFilter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LifecycleFilter

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

Formats the value using the given formatter.

impl Default for LifecycleFilter

fn default() -> LifecycleFilter

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LifecycleFilter

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LifecycleFilter

fn eq(&self, other: &LifecycleFilter) -> 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 LifecycleFilter

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
