Implementations§

Source§

impl HeadObject

Source

pub fn set_if_modified_since(self, if_modified_since: OffsetDateTime) -> Self

If the provided time is earlier than the actual modification time, the request succeeds

Source

pub fn set_if_unmodified_since( self, if_unmodified_since: OffsetDateTime, ) -> Self

Require the specified time to be equal to or later than the object’s last modification time

Source

pub fn set_if_match(self, if_match: impl ToString) -> Self

Require the object’s ETag to match the provided ETag

The ETag verifies whether the data has changed and can be used to check data integrity

Source

pub fn set_if_none_match(self, if_none_match: impl ToString) -> Self

Require the object’s ETag to differ from the provided ETag

Source

pub async fn send(self) -> Result<HashMap<String, String>, Error>

Send the request
