Struct c2pa::assertions::Exif
source · pub struct Exif { /* private fields */ }
Expand description
The EXIF assertion as defined in the C2PA spec section 17.13 See https://c2pa.org/specifications/specifications/1.0/specs/C2PA_Specification.html#_exif_information
This does not yet define or validate individual fields, but will ensure the correct assertion structure
Implementations§
source§impl Exif
impl Exif
pub fn new() -> Self
sourcepub fn set_context(self, context: Value) -> Self
pub fn set_context(self, context: Value) -> Self
sets the @context field for Schema dot org.
sourcepub fn get<T: DeserializeOwned>(&self, key: &str) -> Option<T>
pub fn get<T: DeserializeOwned>(&self, key: &str) -> Option<T>
get values by key as an instance of type T
.
This return T is owned, not a reference
§Errors
This conversion can fail if the structure of the field at key does not match the
structure expected by T
sourcepub fn insert<S: Into<String>, T: Serialize>(
self,
key: S,
value: T
) -> Result<Self>
pub fn insert<S: Into<String>, T: Serialize>( self, key: S, value: T ) -> Result<Self>
insert key / value pair of instance of type T
§Errors
This conversion can fail if T
’s implementation of Serialize
decides to
fail, or if T
contains a map with non-string keys.
pub fn insert_push<S: Into<String>, T: Serialize + DeserializeOwned>( self, key: S, value: T ) -> Result<Self>
sourcepub fn from_json_str(json: &str) -> Result<Self>
pub fn from_json_str(json: &str) -> Result<Self>
creates the struct from a correctly formatted JSON string
