Implementations

impl AttachmentMetadata

pub fn from_tag(values: &[String]) -> Result<Self, SoftchatError>

Parse a complete raw imeta tag.

Errors

Returns SoftchatError::InvalidAttachmentMetadata for duplicate singleton fields, missing required values, or invalid typed values.

pub fn to_tag(&self) -> Result<NostrTag, SoftchatError>

Emit the canonical field order from the accepted Softchat profile.

Errors

Returns SoftchatError::InvalidAttachmentMetadata if the value is malformed or contains a duplicate known field through unknown_fields.
