Struct CompatFlags

    pub endpoint_url: Option<String>,
    pub region_override: Option<String>,
    pub addressing_style: AddressingStyle,

}

Per-profile compatibility flags for S3-compatible storage providers.

All fields have sane defaults that work with AWS S3. Override only the fields that your provider requires.

Serialization uses camelCase for JSON round-trips with the frontend.

Fields

flags_schema: u32

Schema version that emitted these flags. Used for forward-compat migration. Always write 1 for v1 flags; a future bump to 2 signals a format change.

endpoint_url: Option<String>

Custom base URL for the S3 endpoint, e.g. http://localhost:9000. None means use the AWS regional endpoint.

region_override: Option<String>

Pin all requests for this profile to a fixed region, ignoring any region the SDK would otherwise auto-detect.

addressing_style: AddressingStyle

How to form the S3 endpoint URL for bucket operations.

signature_version: SignatureVersion

Signature algorithm. Default V4; V2 is a degraded-compat escape hatch.

checksum_mode: ChecksumMode

Whether to send payload checksums on uploads.

accept_invalid_tls: bool

Accept TLS certificates that fail validation (self-signed, expired). Security risk — only use for development / private networks.

expect_continue: bool

Send Expect: 100-continue on PUT requests. Some proxies and older providers reject the header; set to false to suppress it.

chunked_upload: bool

Use chunked upload encoding (Transfer-Encoding: chunked) instead of setting Content-Length upfront. Required for streaming uploads where the total size is unknown at request start.

bucket_name_validation: BucketNameValidation

How strictly to validate bucket names before sending requests.

unknown: BTreeMap<String, Value>

Unknown flags written by a newer schema version. Preserved verbatim on read and re-serialized on write so a downgrade does not lose them.

Trait Implementations

impl Clone for CompatFlags

fn clone(&self) -> CompatFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompatFlags

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

Formats the value using the given formatter.

impl Default for CompatFlags

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CompatFlags

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CompatFlags

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
