Enum ScanKind 

pub enum ScanKind {
    Ndef {
        mime_type: Option<String>,
        uri: Option<UriFilter>,
        tech_list: Option<Vec<Vec<TechKind>>>,
    },
    Tag {
        mime_type: Option<String>,
        uri: Option<UriFilter>,
    },
}

The kind of scan to perform, which defines which tags are matched.

Variants

Ndef

Only match tags that carry an NDEF message.

Fields

mime_type: Option<String>

Only match tags whose NDEF payload has this MIME type, e.g. text/plain. Android only.

uri: Option<UriFilter>

Only match tags whose NDEF payload URI matches this filter. Android only.

tech_list: Option<Vec<Vec<TechKind>>>

Only match tags supporting the listed technologies.

Each tech list is considered independently and the tag matches when any single tech list matches it, which provides AND (inside a list) and OR (between lists) semantics.

Android only. See https://developer.android.com/reference/android/nfc/NfcAdapter#ACTION_TECH_DISCOVERED for more information.

mime_type: Option<String>

Only match tags whose payload has this MIME type, e.g. text/plain. Android only.

uri: Option<UriFilter>

Only match tags whose payload URI matches this filter. Android only.
