#[non_exhaustive]
pub struct Blob { pub data: Bytes, pub mime_type: String, }
Expand description

Binary blob for passing data in arbitrary encodings.

Binary blobs are both consumed and produced by providers. Note that for many use-cases, we use agreed on MIME types as defined in RFC 47. Providers are able to use custom MIME types if they desire.

We can also store blobs in cells, but for this we use EncodedBlob to allow JSON serialization.

Fields (Non-exhaustive)§

This struct is marked as 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.
§data: Bytes

Raw data.

§mime_type: String

MIME type to use for interpreting the raw data.

We keep track of this, so that we can elide unnecessary calls to extract_data(), and are able to perform migrations on data specified in any of the application/vnd.fiberplane.* types. For other types of data, providers are responsible for migrations, and they are able to include version numbers in their MIME type strings, if desired.

Implementations§

source§

impl Blob

source

pub fn builder() -> BlobBuilder<((), ())>

Create a builder for building Blob. On the builder, call .data(...), .mime_type(...) to set the values of the fields. Finally, call .build() to create the instance of Blob.
